A probable Cooper's Hawk was sighted when we were leaving the headlands around 4:30 pm!! All sixteen team members made it for the Last Day Feast, and with so many team members, we won't even talk about how much food there was.... December 7, 2001 - The skies were clear today on Hawk Hill with the wind gusting up to 25 knots and then calming down in the afternoon.

HawkWatch recorded a total of 132 raptors, 8 species, and 22 hawks per hour. The highlights of the day were 2 Peregrine Falcons that gave us an incredible show. November 24, 2001 - Sat II's dayleader would like you to think that there was no HawkWatch today because we were blown off the hill by the 50 MPH winds. However, that is not the case. Sat II HawkWatchers were all snug in their beds, because their dayleader called the day off at about 6:30 am. Mind you, there was heavy rain then, and 50-60 mph winds, and she didn't want her Watchers on the road for the long distances many of them travel, because the bad weather was supposed to last until noon. OF COURSE, the clouds cleared by about 9:30 am, although the winds continued.... Sat II dayleader maintains her dubious record of calling off days too early. She suspects nothing would be flying in the wind today except the heavies -- bald eagles, golden eagles, ferruginous... Alas, we weren't blown off the hill, but maybe we blew it. Other input on the day's sightings welcomed!! November 23, 2001 - The weather was mostly overcast with high clouds today and rather chilly on Hawk Hill. HawkWatch recorded a total of 194 raptors, 8 species, and 33.7 hawks per hour. The highlights of the day were over 2000 Band-tailed Pigeons, 1500 American Robins, and 360 Cedar Waxwings in flight.

Many of the Red-tailed Hawks hovered around the hill for long periods of time and treated us to acrobatic displays. One Merlin and a few American Kestrels were also seen.

November 15, 2001 - The hawkwatchers made the trip up to Hawk Hill for a total of two hours before the fog came rolling in. Two hours, however, is long enough to spot a Red-tailed Hawk with a white tail! That's right, seriously rare buteo action! Whoooowwweeee! Subspecies, partial albino? Wow! So needless to say that was the rare bird and highlight for the day. We saw a total of 47 raptors, 23.5 hawks per hour, 6 species including: Turkey Vultures, Northern Harriers, Sharp-shinned Hawks, Cooper's Hawks, Red-tailed Hawks, and American Kestrels. What a day!

November 6, 2001 - Absolutely gorgeous day to lay on your back at Hawk Hill and watch the birds a mile above sea level.

The highlights were 3 sightings of Merlins, some really slow and close and some fast, furious, and far away. Far out too! Overall, wonderful day on the hill.
October 31, 2001 - Nasty storms bring wicked, awesome birds! Thanks to those late October showers, HawkWatch got to see a big backup of raptors today. WhooHooo! A total of 288 raptors for the day, including 10 species, at a rate of 49 hawks per hour. Species seen were Turkey Vultures, Red-tailed Hawks, Red-shouldered Hawks, Cooper's Hawks, Sharp-shinned Hawks, Northern Harriers, Peregrine Falcons, Merlins, American Kestrels, and Ferruginous Hawks!

Highlights of the day were a close-flying Merlin and White-tailed Kite, and several male Kestrels stooping on Red-tailed Hawks. October 27, 2001 - It appears that certain species are unable to penetrate the invisible shield that simply must have gone into place with the signing of the Antiterrorism Bill. Hopefully, they will change the settings soon. (Note to gov: Harrier Jet vs. Northern Harrier...) Half expecting to be fogged off, we actually had a full day on the hill, with high clouds, and ominous dark clouds to the north. The wind was mild, but primarily from the north and northwest, but still not much was seen. We totaled 201 hawks, 33.5 hawks per hour, and nine species. Eighty seven Turkey Vulture sightings were joined by Northern Harriers, White-tailed Kites, Red-tailed Hawks (a couple of interesting morphs), Red-shouldered Hawks, Coopers and Sharp-shinned Hawks, Kestrels and a Peregrine Falcon. The highlight of the day was the banding demo, which took place right on top of Hawk Hill, because a large group of boy scouts with axes and rakes were clearing the area around the bunker, and leaving large piles of brush. The juv. female Red-shouldered Hawk was very patient in the docent's hands, and the visitors and HawkWatchers all enjoyed the up-close view. October 26, 2001 - HawkWatch wasn't able to begin their count until 10:30 am due to foggy conditions and was only out for a total of two hours, again due to the fog.

It remained warm and clear all day. 11 species of raptor were seen, including all four falcon species: Kestrel, Merlin, Peregrine Falcon and Prairie Falcon.

The total number of raptors seen today was 525, and the rate of raptors per hour was 87.5. Especially large numbers of juvenile red-tails moved through from the West between 2 and 3:30 p.m. October 24, 2001 - Under clear skies today HawkWatch counted 473 birds including 11 species for a total of 78.9 hawks per hour.

October 15, 2001 - Being on Hawk
Hill today was similar to looking out over an old ghost town in the
southwest-it was hot, dusty, and no action. Not much bird action that
is. But hey, that's what happens when the wind dies down or comes out
of the south. The total for today was 255 raptors, that's 42.5 per hour.
Nine species were seen including: Turkey Vulture, White-tailed Kite,
Northern Harrier, Sharp-shinned Hawk, Cooper's Hawk, Red-shouldered
Hawk, Red-tailed Hawk, American Kestrel, and Peregrine Falcon. Highlights
for the day were definitely looks at 2 adult Peregrine Falcons, distant

October 13, 2001 - Feeling HOT,
HOT, HOT!! We were treated to incredibly clear skies today -- practically
unlimited visibility. And if you're from the Bay Area, you know that
happens for a reason -- NO WIND. Temperatures were between 85 and 90
degrees most of the day, with little more than a breeze, early on from
the south, and then shifting slowly to southwest. Activity was pretty
steady until around 1:00 PM or so, when things really slowed down, the
heat was on, and the birds were flying very high. The total count was
335 raptors, 55.8 hawks per hour, and eleven species. Highlights of
the day were great looks at Peregrine Falcons, two close Merlins, one
Broad-winged Hawk, one White-tailed Kite - nice and close, and several

Red-shouldered Hawks, White-tailed Kites, Merlins, Cooper's Hawks, Sharp-shinned

activity today was a little slower than what's more typical for this
time of year. But that of course is affected by some less than ideal
weather conditions for birds interested in soaring. Basically, I'm talking
about fog. A little too much for major flight activity, as well as hawk
spotting. Nonetheless, the HawkWatchers had a good day, 7 species, 146
hawks total, 41.7 per hour. Species spotted are Turkey Vulture, Northern
Harrier, Sharp-shinned Hawk, Cooper's Hawk, Red-shouldered Hawk, Red-tailed
Hawk, and American Kestrel.

out around noon today and stayed clear for a little over an hour. In
that hour we saw a beautiful display of raptors including Turkey Vultures,
Red-tailed Hawks, Northern Harriers, Cooper's Hawks, Sharp-shinned Hawks,
American Kestrels, Red-shouldered Hawks, and Broad-winged Hawks. Total,
we saw 65 hawks. Not bad for an hour, eh?

morph Broad-winged Hawk. The first Swainson's Hawk of the season was
also seen.
September 29, 2001 - The day
started out a little bit slow, with beautiful, warm temperatures, and
no wind. This was a good thing for the Saturday II team, which had been
fogged off since the beginning of the season. We had to warm up, and
we had a good chance to do so. We worked on our accipiter ID as mostly
Sharp-shinned Hawks, and then Coopers Hawks, moved through. Our activity
was rounded out with the beautiful West Coast Red Tails and some great
close looks at Broad-wings as well. (They always sneak up on us, to
confound for a moment...) The count ticked up as the day went on, primarily
with accipiters. The highlight was an unusual hour between 1 PM and
2 PM, when four juvenile Ferruginous Hawks flew by, the first starting
over by the Slacker Hills and then the others coming through the North
saddle and right over Hawk Blind in front of us, giving us great looks,
and one additional later from Kirby Cove, which had potentially been
sighted earlier but wound around the hill to appear for another sighting.
We had few falcons though, only Kestrels, and we wound up the day with
461 raptor sightings, including eleven species: Turkey Vultures, Red
Tails, Red Shoulders, Sharp Shinned & Coopers Hawks, White Tailed Kites,

September 21, 2001 - The fog
slump has been stopped! Today's HawkWatch team made it up to Hawk Hill
, despite the fog. In 1 hour and 40 minutes of slight fog, we managed
to catch a glimpse of 6 different species, 85 raptors total, with an
average of 51 hph! Not bad for a foggy day! The 6 species seen were:
Turkey Vultures, Red-tailed Hawks, Cooper's Hawks, Sharp-shinned Hawks,
American Kestrels, and Northern Harriers. We will not let the fog hold
us back!
September 20, 2001 - More fog!
HawkWatch was again kept from Hawk Hill due to fog.
September 19, 2001 - Today was foggy again! It must
be the price we have to pay sometimes for getting to see as many raptors
as we do. However, fog can't last forever, stay tuned for the next hawk
watch reports. As soon as this fog clears the sky will be painted with
hawks!
September 18, 2001 - The HawkWatch
was fogged out for the fourth consecutive day. Oh where is the sun?
September 17, 2001 - The HawkWatch
was fogged out ... again!
September 16, 2001 - The HawkWatch
was fogged out.
September 15, 2001 - The Saturday
II team went up to the hill at around 11:00 am, with high hopes the
fog would clear, as it had the day before. Every time we felt the warmth
of the sun peeking through, our hopes were quickly dashed by the next
thick blanket delivered by the Fog God. No amount of sun dancing, fist
shaking or otherwise scientific means attempted by the team had the
desired effect. Instead, we focused on Sharp-shinned Hawk Silhouette
ID 101 (sharpies in the fog), Sharp-shinned Hawk In the Hand ID (Banding
demo), and finally left Hawk Hill at around 1:45 PM. As usual, we had
fun anyway just being together!
September 14, 2001 - Due to the nearly ever-present
fog, the HawkWatch didn't get started till 11:15. The weather was clear
after that and the HawkWatch had 277 raptor sightings for 65.2 Hawks
per hour. The highlights of the day were looks at a Ferruginous Hawk
and several Broad-winged Hawk sightings.
September 13, 2001 - Fog seems
to come in pairs, doesn't it? Like yesterday, the HawkWatch was called
off today due to heavy fog. But have no fear, the HawkWatch and our
flying friends will be back again soon enough.
September 12, 2001 - HawkWatch
was fogged off Hawk Hill today.
September 11, 2001 - A somber
day on Hawk Hill saw silent skies and long gaps in bridge traffic. An
initial rush of sightings slowed as the fog played tag with the HawkWatchers.
Midday saw off the fog and hawk traffic picked up with frantic spells
pacing the balance of the day. We recorded 10 species and a grand total
of 476 birds with a Hawks per Hour rate of 79.3. Our highlights included
a juvenile Golden Eagle and a Prairie Falcon. The juvenile Red-tailed
Hawk numbers continue high with today coming in at 167. Other notables
were 9 Northern Harriers, 5 Osprey, 3 White-tailed Kites,a total of
231 Red-tailed Hawks, 56 Sharp-shinned Hawks, 44 Cooper's and 23 undocumented
Accipiters. 74 Turkey Vultures competed our total.
September 10, 2001 - HawkWatch
reported 363 raptor sightings including 11 species. That's 60 Hawks
per Hour! Highlights of the day were a Golden Eagle, a Peregrine Falcon
and a Prairie Falcon.
September 9, 2001 - A lovely day up on Hawk Hill. Altogether we saw 224 birds in the six hours up on the hill, giving us 37.2 hawks per hour. Today was a heavy Turkey Vulture day, almost 50% of the day's birds were of the vulture persuasion. The rest of the birds seen today were of 5 different species: Osprey, Red-tail Hawks, Cooper's Hawks, Sharp-shinned Hawks, and Northern Harriers. Not bad for a Sunday afternoon! September 8, 2001 - An overcast windy day on Hawk
Hill today but HawkWatch stood up to it and recorded 330 raptor sightings
for 55 Hawks per Hour. Most common sighting was the Turkey Vulture followed
by the Red-tailed Hawk. There was one sighting of an Osprey as well.
September 7, 2001 - The day started
off with just a few patches of fog but as the day progressed the fog
came in on a cold wind and the HawkWatch left Hawk Hill about noon.
In the time they did have on Hawk Hill they recorded 65 sightings of 4 species for 37.1 hawks per hour. Species seen were Red-tailed Hawks, Cooper's Hawks, Sharp-shinned Hawks and Turkey Vultures. September 6, 2001 - 9 species today-Turkey Vulture,
Osprey, White-tailed Kite, Northern Harrier, Sharp-shinned Hawk, Cooper's
Hawk, Red-shouldered Hawk, Red-tailed Hawk, and American Kestrel! Highlights-111
juvenile Red-tailed Hawks, 11 Red-shouldered Hawks, 2 accipiters for
the id study, beautiful looks at the White-tailed Kites. What a day!
And let's not forget, today was the highest sightings day yet-316 raptors
in 6 hours, that's 52.7 hawks per hour! WOW! Bring it on raptors, the
HawkWatch teams are ready for ya!
September 5, 2001 - What an amazing
day up on the hill! An 11-species kind of day. The total raptors seen
on this Wednesday, September 5th were 217, with an average of 36 hawks
per hour. Whoo wee! The list of species seen are as follows: Red-tailed
Hawks, Turkey Vultures, American Kestrels, Osprey, Cooper's Hawks, Sharp
Shinned Hawks, Prairie Falcon (yippee!), Broad-winged Hawks (that's
right!), Northern Harriers, White-tailed Kites (real close look at two),
and Red-shouldered Hawks! What a day!
September 4, 2001 - Fog drove the HawkWatch from Hawk Hill today. September 3, 2001 - Labor Day isn't just for humans you know, hawks need a break too. The raptors of the pacific states were in no hurry to move through the Marin Headlands today. Whether that's due to heavy fog or the national holiday of rest and relaxation is a matter of hot debate. However, the hawk watchers did catch a glimpse of some workaholic raptors today. Our research shows that no one particular species is more prone to working on holidays; of the nine raptors seen today (1.33 Hawks Per Hour), five were different species! Osprey, Turkey Vultures, Red-tailed Hawks, Northern Harrier, and Cooper's Hawks; they just don't stop! Until next time, and for the meanwhile, learn something from the hawks: take a break! September 2, 2001 - The fog was serious this morning, but fortunately for the hawks and their observers, it cleared for a few hours so the raptors were flying all over! The total sightings today were 192, making a 35 hawks per hour day! Not bad for a day ruled by fog, eh? Eight different species were seen including Red-tailed Hawks, Turkey Vultures, Peregrine Falcon, Osprey, Cooper's Hawks, Sharp-shinned Hawks, American Kestrels, and Northern Harriers. Whoo wee! Most of the raptors seen today were American Kestrels and juvenile Red-tailed Hawks. September 1, 2001 - The HawkWatch
team waited, and waited, and waited, for the fog to clear. While we
were waiting, looked for birds around rodeo Lagoon, with good success,
and we did a short hike on the Bobcat trail, during which we saw Turkey
Vultures, juvenile Red-tailed Hawks, White-tailed Kites, American Kestrels,
juvenile or female Northern Harrier (couldn't get a good view due to
the glare...), adult male Northern Harrier, and a Sharp-shinned Hawk.
Great views of the White-tailed Kites. Some of us also saw a bobcat,
which crossed the path between where the group of us had separated!
The skies looked like they were clearing, so we went up to the hill
around 12:15 PM, but it was a no go. It was a treat to watch the banding
demonstration instead. No HawkWatch data was collected. For those interested,
we spotted western bluebirds in the field below the rifle range.
August 31, 2001 - Ah the summer
fog was in again today and the HawkWatch didn't get up to Hawk Hill.
They did do some birding below Hawk Hill and saw Red-tailed Hawks, American
Kestrels, Turkey Vultures as well as Blue-gray Gnatcatchers and Scrub
Jays.
Tomorrow (September 1) there will be a HawkTalk on Hawk Hill at noon and a banding demonstration at 1:00 PM (weather permitting) August 30, 2001 - The day was
full of fog in the Marin Headlands. Unfortunately, it did not subside,
so today's HawkWatch was canceled. Stay tuned for more from the GGRO.
August 29, 2001 - The HawkWatch was fogged out today. They had to fog-get about it. August 28, 2001 - Day 9 of the season started at 9:30 with a temperature of 71. The winds were light and variable, a distant fog bank over the Farallon Islands and a smog layer over the east bay. We recorded 268 raptor sightings including 7 species, with a hawks per hour rate of 44. Red-tailed Hawks as usual topped the list, with a final tally of 30 adults, 120 juveniles, and 10 undocumented Red-tailed Hawks. A large kettle of red-tails hung around for an hour over Slacker. Midday we saw the wind pick up and the HawkWatch dawned an extra layer, but only for an hour, and then it was back to T-shirts. Other notable sightings were 9 Osprey, 2 juvenile Northern Harriers, 10 American Kestrels, 5 Sharp-shinned Hawks, and 4 Cooper's Hawks. Turkey Vultures topped off at 63. August 27, 2001 - The weather on Hawk Hill today was sublime ... close to perfect. 290 raptors were recorded for 48 hawks per hour. Ten species were sighted. The highlights were a Broad-winged Hawk, White-tailed kite, Osprey, Northern Harrier, male and female American Kestrels as well as the "usual suspects." August 26, 2001 - The fog cleared relatively early in the Headlands this morning. The HawkWatch team was able to start the count by 10:30. Total hawks for the day-160! Turkey Vultures and Red-tailed Hawks dominated as usual for this time of year. Other common visitors for the day: Cooper's Hawks, American Kestrels, and Northern Harriers. The highlight for this August 26th was definitely the dark morph and rufous morph Red-tailed Hawks seen coming from the north. August 25, 2001 - The fog cleared about 11:00 AM with the wind from the west. There were 260 Hawk sightings (45 hawks per hour) with the Red-tailed Hawk being the most common along with Turkey Vultures. Nineteen American Kestrels were counted as well. August 24, 2001 - The HawkWatch team did get up to Hawk Hill today but the weather didn't cooperate... it teased and tantalized but no raptors were seen, just fog. August 23, 2001 - Fog again today, brought in from strong westerly winds. Like yesterday, today's fog was especially thick and wet so the HawkWatch team didn't get up on Hawk Hill. August 22, 2001 - Fog again today, therefore the HawkWatch was declared a skunk at 1 PM. But as always, there is hope for tomorrow. August 21, 2001 - The day started clear. The fog came in for a bit but cleared so that HawkWatch had a good early season day...a great day! Sightings of note for the day were a Prairie Falcon, juvenile Bald Eagle, juvenile Golden Eagle and several Osprey. 249 raptor sightings were made comprised of 11 species. That's 41.5 Hawks Per Hour. August 20, 2001 - Fog, fog, fog. Fog so thick you couldn't even see it move. The HawkWatch team instead took a hike through Gerbode Valley, where we were fortunate enough to see a Great Horned Owl fly in a grove of eucalyptus. Also, we saw one Red-tailed Hawk kiting. We hope for a clear day tomorrow. August 19, 2001 - No report for
HawkWatch was filed today.
August 18, 2001 - After getting to know each other -- and there are lots of us -- we waited for the fog to clear while looking at some slides, etc. The team got up to the hill at about 11:30 am, and we we had limited visibility with some windows of blue sky. We saw about 30 raptors including American Kestrels, Peregrine Falcon, juvenile Red-tailed Hawk, Turkey Vultures, Cooper's Hawks and Sharp-shinned Hawks, and ended our short day with a long look at a spectacular juvenile Northern Harrier. August 17, 2001 - Report for
today at the hill: No fog today. It was clear with a bit of wind. During
the two hours that HawkWatch was on Hawk Hill, they say 46 raptors for
23 hawks per hour. There were 4 species seen - Red-tailed Hawks, American
Kestrels, Northern Harriers and Turkey Vultures.
August 16, 2001 - Report for
today at the hill: Fog! Lots of fog. However, it did subside here and
there; enough to spot a few Red-tailed Hawks and Turkey Vultures.
August 15, 2001 - The fog was in so the HawkWatchers weren't. August 14, 2001 - Fog! Nothing
but fog! Pretty much no visibility. The HawkWatch team did however manage
to spot 1 Turkey Vulture.
August 13, 2001 - Yet
another gorgeous day on Hawk Hill! Slight winds from the west brought
in warm breezes averaging about 65°. Sunshine was ever-present apparently
making for lots of thermals around Hawk Hill. The Turkey Vultures and
Red-tailed Hawks took full advantage of those, circling about the hill
all morning.
The grand total: 33 Turkey Vultures, 19 Red-tailed Hawk, 1 Sharp-shinned Hawk, and a couple far off unidentified raptors. Stay tuned for more. August 12, 2001 - Here's the
scoop for today at Hawk Hill. The highlight of the day ... one Osprey
"packing a lunch,"(the fish remained unidentified). Thirteen total Red-tailed
Hawks were seen kiting about the hills of the Marin Headlands as well
as 4 Cooper's Hawks, an American Kestrel, and a hand full of Turkey
Vultures. That's a grand total of 28 hawks in 2.5 hours, for an average
of 12.4 hawks per hour! Weather today was beautiful and clear again
for the 3rd day in a row. Gentle breezes from the north west, and a
high of 68°F. Another great day on the hill!
August 11, 2001 - The watchers
got up on Hawk Hill after 10:00 and were greeted by sunny skies with
only a few clouds. There were some very good sightings today: a Prairie

per hour was 25.
August 9, 2001 - The HawkWatch
team spent an hour on Hawk Hill in the fog waiting for the fog to clear.
As the fog did not clear, no hawks were seen.
August 8, 2001 - The fog was in
brought by a south west wind. Due to the fog no HawkWatch was conducted.
August 7, 2001 - Day two of HawkWatch
2001! The watchers didn't get up on Hawk Hill until nearly noon due
to fog. Nonetheless, they were rewarded with sightings of an Osprey,
American Kestrels, Red-tailed Hawks and Turkey Vultures. The watchers
left the hill at about 2:30.
