John Blakeman on the Boston Train Station Hawk With A Good Capture Method, Plus Video-The Hawk Gets Knocked Out


Photo by Donna Browne Juvenile Cooper's Hawk

The second post of yesterday involved a supposed Red-tailed Hawk who'd flown into a Boston Train Station and was perched up top in the rafters considering the situation. Scroll down if you've not read it and seen the video. Sally of Kentucky, caught it first.... Oops that's no Red-tail that's a Cooper's Hawk!

I also found this news story, seems that the Coop had been up there for a week already by December 5th.

Here is what Ohio Red-tail expert John Blakeman had to say about the matter--

Donna,

The Boston hawk is a Cooper’s Hawk, not a red-tail. The plumage is all wrong for a red-tail, and a red-tail would never get itself perched way up on the interior beam this bird was photographed on.


Cooper’s Hawks are famous for getting inside buildings like the one shown. I’ve dealt with a number like this. They shoot easily and naturally under and through open doors, right into the interior relative darkness. This matches exactly what they do when shooting through woodlots, dashing under limbs and downed trees in search of birds. But in a forest, there is always an opening on the other side of the "entrance." Not so in buildings.


And the falconer shown briefly with a mouse-baited "bal-chatri" trap (pronounced "ball-shot-ree") is unlikely to capture the hawk. Cooper’s Hawks seldom drop down to the ground in pursuit of mice. They are primarily a bird hawk. The trap should have been baited with freshly-caught house sparrows, which when properly handled will dash back and forth inside the cage, luring the hawk down to the apparently injured sparrows inside.

The trap is covered with small nylon snares that enclose around the hawk’s legs and toes when the hawk attacks the lure animals inside. The hawk is uninjured in any way.

But the Cooper’s Hawk won’t come down to a pair of white mice, especially in a busy train station.

Thank you John for sharing your experience and knowledge of the species with the rest of us. Here is another link for a piece of video, from WDEF, Boston, as The Animal Rescue League attempts to rescue the Cooper's Hawk in the train station.

On a lighter note, in case there was any doubt about the ancestors of birds being dinosaurs, here is Quicksilver doing an imitation of his many times Great Grandfather.

The Woodman's Feather Mystery and a Strange Duck


Photo Donna Browne
Remember back in early October, I discovered a great many feathers surrounding the Woodman Supermarket in Janesville, WI?


There were feathers in the gravel, under the bushes, and sticking to the grass in the lawn. At first I thought they were all pigeon feathers but on closer examination I realized there were a good many gull feathers there as well.

Looking around I didn't see a single member of either species. What was going on? Well...

Upon leaving the store the other day, I looked up to see a kettle of birds circling above a small strip mall kitty corner from Woodman's.

On closer examination they looked like gulls.

I hit the brakes and abruptly took a right, almost hitting a couple pigeons that had flushed suddenly from the ground. (Glad to miss the pigeons. But sorry, I missed the shot. They hot winged it out of there.) Then I looked to see where they'd come from.

Just as a flock of sparrows came out of the bushes and repositioned themselves under a---WHAT? A bird feeder! Look up at the stores in the photo of the mall above. There is a Wild Birds Unlimited and they have a number of feeders in the small green space between the road and their parking lot. Now look in the upper right hand corner of this photograph. See the beige building with the orange roof trim? That is Woodman's, where all the feathers are laying everywhere.

Thinking back I've seen Red-tailed Hawk circling about an 1/8 of a mile from this point several months ago. And three years ago I watched a Cooper's flying at car roof level from small tree to small tree in the Woodman's parking lot.
Mystery solved. Obviously the bird feeder is the draw for the seed eaters, (plus there are the wind currents around the little mall creating a place for birds to kettle up) and that nice flat roof of Woodman's is the dining hall for any raptors who happen to be taking their dinner from the birds availing themselves of their dinner at the feeders.
I always feel much better when I've figured it out. Whatever "it" is at any given moment.

Donna,
I was at the NYBG earlier today trying out my new toy. The mystery duck there seems to have attracted a friend. Here's some video I shot.

I've attached a photo. Is this another farm duck?

Pat,

It looks like a hybridized individual to me. One that is at least partially a "farm duck".
