2015 June 16 Wildcat raptor update – part i (red-tails)

There is nothing quite like seeing young animals play, and it has been such a treat on my sunset/twilight wanders lately to see a pair of fledgling red-tailed hawks in Wildcat Canyon cavorting in the strong winds up in the hills for the past week or two. They are still sometimes unsteady as they soar in the air, and during their landings – wheeling awkwardly in the winds, or alternating repeatedly landing and taking off from a hilltop trying to ride fast moving gusts, like a feathered, bouncing ball. Sometimes their parents were silhouetted in the background above them, unmoving in the strong winds as if hanging from an invisible thread in the sky as they hunted. For the first week or so, every time the two young ones were in the air, they were loudly vocalizing non-stop, as if shouting “holy shit I’m flying, holy shit I’m flying!!!” That’s how it felt, watching their exuberance in the sky.

Despite their awkwardness at times, there were other times that they seemed to be quickly mastering flight in the high winds – chasing each other over the hills and around tree tops, stooping and diving on one another, locking talons in the sky, and pushing each other off of perches – even “barrel rolling” in the sky like ravens often due (an acrobatic maneuver during which they flip over on their back for a few moments in the sky). Sometimes I forget that I’m without any wings as I watch them, feeling like at any moment I could jump up and join them. It looks like just about as much fun as any living thing can have.

Hopefully this pair will survive longer than last year’s young – there were three from what were likely this same pair of adults, and none of them survived more than two weeks after fledging. Once night comes, it is the domain of the great-horned owls … and there are a lot of them here. It’s encouraging that they’ve lasted this long, soar on young ones!

red-tails in NYC – the legacy of Pale Male

I was walking through Union Square in New York City this week. The city had its seasonal holiday vibe happening, despite the relatively warm weather and steady rain that was falling. As I strolled from the subway in the park with the many other people, in this man-made clearing among the tall buildings around it, I suddenly had an impulse to turn around and look up. I turned almost fully around, and above me, a flock of rock doves (pigeons) was in determined flight – and in fast pursuit was a familiar form that at first didn’t register with my brain due to the surroundings. A red-tailed hawk!

The hawk made a reasonable attempt at grabbing one of the pigeons in flight, then it alighted on top of one of the “canyon” walls at the north end of the square. It was a comical sight – the red-tail was sitting on the east side of the building, its head turning back in forth in what seemed to be bewilderment, and about 30 pigeons sitting on the west side of the building about 40 feet from the hawk. It was as if there was an official “time-out,” and the players in this game were on the sidelines waiting for the next play.

It seems I was the only person to see this happen, but luckily my spinning around in the middle of the square watching birds flap around, and staring up in the rain at what probably seemed like nothing to the casual observer, was just a minor crazy behavior in this place. I couldn’t help but smile at the whole scene. Since before I can remember I’ve had a connection with Red-Tailed Hawks, and to see one here in amid the concrete and steel was like seeing an old friend. What made me turn around? I don’t know, but I’m thankful for it.

Red-Tails are adaptable animals, but they have been one of the more recent additions to the city-scape, joining some of the other animals that have been able to survive in the shadows of intense human development like Raccoon, Opossum, Rat, Mouse, Bat, Fox, Crow, Pigeon, Gull, Peregrine Falcon and Others. It made me think about one of the first documented red-tails that came to call a city, this city, home – a hawk named Pale Male.

Pale Male (so named due to his distinctively pale plumage) made a big impact on my life, as he has on the lives of many others. I was living in New York City in 2004, on the Upper West Side near Central Park. It was a particularly hard time in my life, and I was struggling to find a connection to the Earth in the middle of the chaos of the city. I would walk through the Park, through The Bramble, almost able convince myself I was somewhere else in that island of earth and plants and animals smack in the middle of one of the biggest cities on Earth. Once through, I would go to the Boat Pond and sit, hoping for a glimpse of Pale Male or his mate or offspring. We were kindred spirits, neither born of the city, but both in it. Surviving. It was surreal seeing this large raptor gliding above the yellow taxi cabs on 5th Avenue, or perched on the railing of a balcony on an apartment building. But there he was.

And still is. Life in the “wild” is hard, and there are many perils for any animal to deal with – especially in the city. In addition to all the regular threats, city birds deal with high densities of people, fast moving traffic, and most the deadly threat, rat poison. Many animals consume rats or pigeons that are still alive but have ingested poison, and can die from acute poisoning or from an accumulation of toxins. Not only was this bird one of the first to be documented making his territory in a large city – nesting and rearing young – but he’s still around. He has had many young, and some of those birds now also call parts of the city home. It’s an amazing saga. He has seen many of his mates succumb to rat poison or other perils, yet he still calls 5th Avenue home. It’s estimated that he hatched in 1990 – making him almost 25 years old!!

Much of his life has been documented in photographs tirelessly by a fellow named Lincoln Karim – his website, palemale.com, has some amazing photos of this bird and other wildlife in Central Park. He is out there photographing him almost everyday, since 2002! When I would go to the Boat Pond in Central Park, Lincoln often had his “rig” sitting out there – a large cart that carried his telescopic lens that was the size of my torso, and a large monitor screen so that other people could see the bird as seen through his high magnification lens. Many many thanks to Lincoln for his documentation and for sharing all his work and allowing us to be part of Pale Male’s incredible life.

Thanks also to Marie Winn, author of Red-Tails In Love (about Pale Male and one of his mates) and one of the original observers of Pale Male. She has documented his life beautifully in her book and also on her blog where she also chronicles the wildlife of Central Park.

And thanks to Rachel Carson and all the people who worked (and work) hard to regulate pesticide use and raise awareness about raptors and wildlife, which has allowed Red-Tails and many other bird species to rebound to the point of repopulating to healthy numbers once again.

Was the bird I saw in the square a descendant of Pale Male? It’s very likely, but hard to know for sure.

Thank you Red-Tailed Hawk.


fledge week!

During this past two weeks I’ve had the fortune to see a lot of local raptor young and fledglings – peregrine falcons, red-tailed hawks, northern harriers, white-tailed kites, osprey, and even one black hawk / red-shoulder hybrid. I’ll have more detailed blog posts and the stories about each of these soon, but for now here are a few pictures.

lots of eyasses!

so many babies right now! in addition to the exciting black hawk / red-shoulder nest and eyas (in my last post), i’ve gotten to see some other fun sites.

the three eyasses at the fruitvale bridge have successfully fledged and are learning to fly. when i was there last week, they were still unsteady in their flight, and one was doing a lot of “practice flapping” while gripping tightly onto the bridge span. so fun to watch. he took a little time to stare down at the strange two-legged staring up at him. when the adult female showed up (empty taloned), one of the young kept harassing her and pushing her off her perch. they are a hungry lot!

i stumbled on a nest that i hadn’t ever seen before, after hearing the young begging for dinner. this red-tailed hawks nest near wildcat canyon should be vacant very soon – these young are looking ready to go. i saw their parents hunting until well after dark trying to keep their bellies full, not an easy job!

i’m still hopeful that i’ll get to see some young harriers soon, for surely the behavior of the the pair (pictured in some previous posts) in the marsh by the bay indicates they are around.

dark morph red-tailed hawk

2-IMG_9670 raw edit v1

i ran into another old friend on friday … a dark morph (or rufous/intermediate morph) red-tailed hawk that has spent the last few winters in berkeley. it’s fun when i get to know an individual animal, and this one has been around for a few years but i just saw her for the first time this season about a week ago. i was happy to see her again.

when i first saw her we gave each other a little wave (ha!)

1-IMG_9669 raw edit v1

right about the time that i saw her, a huge flock of crows was moving through the area and it didn’t take long for some of them to spot her too. crows love to harass red-tails, and today was no different. first one or two took up the chase, and soon there was a flock of close to 50 crows escorting her out of the area.

i’ve mentioned this before, but there are some corvid researchers (i can’t remember who) who say that this mobbing behavior could be a corvid “right of passage” – which makes some sense to me because there is very little reason that i can think of for the birds to do it other than fun or to establish social ranking.

Sunday was a warm and clear day on the coast, strange weather for January – it felt like summer (well, summer anywhere besides the coast and the Bay area). We started the day by witnessing some interesting behavior by a couple of deer that caught our attention. The deer, which appeared to be doe and a yearling (nearly the same size), were standing with heads raised and their focus on something in the chaparral to the north of us. The yearling took off trotting, then bounding, right towards the path we were on, seemingly unconcerned with our presence. It then stopped and turned around, bounding back to its mother. The two of them then started a slow walk in the direction of the threat, with the mother in the lead. Shifting our position back down the trail, we were able to see what was causing the concern …

I was only able to catch the tail-end of the bobcat as he disappeared into a coyote bush (for the moment now a bobcat bush) – a large male that uses this particular territory who’ve we’ve tracked and seen around here before. Although I think it’s rare for bobcats to take down full grown deer in this area, fawns are fair game. This particular young one is probably big enough to be safe, but given the respect that the deer on this day showed towards him, and on another occasion when I witnessed his presence disturb them, I’d say he is still viewed as a threat. He seems to be a large bobcat based on his tracks and scat.

The most interesting part of this whole interaction was when the deer started to FOLLOW the bobcat – the doe literally walked right to where the cat had disappeared, and she seemed to be chasing HIM out of the area! Good stuff.

On the way in to the lagoons, I spotted an American bittern in a small pond along the pathway – I’ve seen one on the far shores of the larger lagoon, but never one so out in the open here. It was shaping up to be another good day, with lots of live animal sightings. Later in the day on the return trip it was still there and posed for some pictures in the beautiful light.

As we approached the lagoon, a resident great-blue heron was hunting in the shallows.

There were quite a few sets of trails and tracks on the dunes, but the striped skunks were most prevalent. This is their mating season, during which they really seem to be wandering around outside of their normal areas with higher frequency – sadly it is also marked by the large number of road kill skunks at this time of year. Notably absent was the female bobcat that usually patrols this area. It is also breeding season for the cats, so her daily patterns are likely interrupted by the breeding impulse. I also spotted at least one golden eagle soaring above the hills, only the second time I’ve seen one in this particular area. Along with a ferruginous hawk sighting (a somewhat rare winter visitor in this area) and the great view of an intermediate morph red-tailed hawk, we had some great raptor and other bird sightings. During the day at various times the family of otters was visible on the upper lagoon, but I never really was close enough for any pictures. Just their presence is a joy, watching them even from afar is so fun.

As we were resting by the lagoon, a pie-billed grebe made it’s way out of the shallows by the cattails with quite a prize – after straining to identify what it was, we realized it was a small bass! The grebe paddled around with the fish in its beak for at least five minutes, occasionally shaking it and twice losing it in the water, but diving down and quickly recapturing it. Finally, after almost ten minutes, it downed the fish whole!!

Impressive.

Another great day out there, I’m so thankful for that place and to be able to wander in it. Thanks also to Richard Vacha and everyone who participated in this Marin Tracking Club excursion for making it a fun and educational day.


rough day

Rough-legged, that is.

Hawk.

Last Saturday I helped lead a raptor tour at Lynch Canyon for Solano County Land Trust with Larry Broderick of West County Hawk Watch … and I don’t think anyone was disappointed. Two rough-legged hawks made an appearance along with the many resident red-tailed hawks, white-tailed kites, kestrels, northern harriers, red-shouldered hawks, turkey vultures, and a pair of golden eagles. We also had two peregrine falcons soar over us. Good day. Rough-legged hawks breed in the Arctic and it is uncommon to see them this far south, though this year there seem to be more of them than usual during the winter here in the Bay Area.

Check out some of the other tours that Larry Broderick leads at the Sonoma Land Trust and Solano Land Trust websites – he is the raptor magnet and always fun to tour with.

dark morph extravaganza

Lot’s o dark morphs lately! Delicious.

The rains have passed and the light was perfect for a few more shots of the intermediate/dark morph in Berkeley …


day of the dark morphs

We saw a dark morph ferruginous hawk in Sonoma County the other week (!!), it’s been hanging around with a light morph ferruginous hawk in an area that also has at least one dark morph red-tailed hawk (probably the one that I photographed and posted here from last year).  A rare treat in Sonoma County to see ferruginous hawks of any plumage – the largest hawk native to the United States.
