I will try and keep everyone updated as much as possible on activities of the falcons this year, we do have another pair at the bridge and the Canadian Peregrine Foundation (CPF) have installed a new nesting box high up on the Bridge. Maybe I should of wrote inside the bridge as Mark Nash from the CPF had a window removed and set the box inside of tower and then secured it.
The box was installed a week ago Friday and the birds didn't seem that interested in it until today when one of the pair spent many hours relaxing inside. The other bird (the female I assume) stayed down on the rail where past nest have failed.
Best of luck to this year's falcons.

Also, photo #1 of the nesting box was taken by photographer Tom Rook who had an execellent camera with lens that was about a foot and half long.
Thanks to Tom :rock: (www.stockfullofnature.com)

Photo #2 was taken and sent in by member madmax.

Photo #3 Forum photo.

Mark Nash from the CPF was back at the Bridge today to add some finishing touches to the nesting box, only the female was around to watch and she didn't seem too happy about all the work that Mark was doing.
I did tag along and took a few pictures.

Photo #1- That's Mark adding more gravel to the bottom of the box.

Photo #2- The Peregrine landing just below the nesting box.

Falcon is looking for love

Dundas the falcon is looking for love
By Rob Faulkner
The Hamilton Spectator
(Mar 26, 2007)
Dundas -- the one-legged peregrine falcon born on the Sheraton Hamilton Hotel ledge -- is back, with a healthy case of spring fever.

Local birder Tom Thomas spotted the three-year-old raptor at the Burlington Lift Bridge, the first local sighting of Dundas since early 2006.
He was trying to entice a female falcon to nest -- a randy move, considering his amputated limb had nearly spelled certain doom for the bird of prey.

"He's hell-bent on nesting," said Audrey Gamble, monitor for the Hamilton Community Peregrine Project. "His hormones are in the right place."

Dundas was born with three sisters on the Sheraton in 2004, to longtime resident Madame X.

A rascal, he loved diving low into narrow spots, emerging unscathed. But in fall 2004, he was seen with a stump for a leg. It seemed a death sentence.

Falcons need both feet to mate, fight and hunt and live to age 12.

But Dundas was resourceful.

By 2005 he was living in the Old Navy sign at Lime Ridge Mall, perfecting a technique that saw him chase pigeons into the glass, then balance on one foot to tear them into bite-sized pieces.

Thomas, a retired realtor from Carlisle, hopes the blue-grey raptor has taken up residence at the bridge for nesting. His photographs of Dundas there have excited the birding community. The last notable Dundas sighting was in Kitchener last June, when he had a female companion.

Dundas hasn't been able to start a nest, leading some to wonder if he, or his mates, are infertile.

"Everything else seems to be right on track, except for the foot," Gamble says. She speculates that Dundas may have explored a farmer's leghold trap too closely, but it's uncertain.

Now he's ready to nest. Unlike songbirds, peregrines don't build fancy nests. They find a flat spot, like a bridge girder or a gravel bed scrape.

This winter, several peregrine falcons have been flirting at the Lift Bridge.

It's a common spot for falcons coming back north, like a man-made cliff ledge.

"The timing is right on par. The birds downtown have been mating and we are expecting an egg anytime now," said Gamble.

The first egg last year was spotted March 29 and the first chicks are hatched around Mother's Day.

If Dundas the one-legged lover was successful in mating, an egg would appear in two weeks. But the trick, Gamble says, is whether he can balance on the female to get the job done.

"With only one foot, I wonder how he's going to do that. One biologist said the process is so quick. I think he'll be able to manage."

HOW TO SPOT A RAPTOR

* Long, pointed wings. Strong flying ability with speeds up to 320 km/h * Prefer tall perches and ledges. Have a piercing call * Head feathers look like a dark hood with chinstraps. Dark blue-grey back and rump but white under throat, wings and chest * Young hatchlings fluffy and white * Attack prey in mid-air. Eat gulls, pigeons, doves, waterfowl, shore birds, sometimes songbirds * See Sheraton nest live at hamiltonnature.org/hamfalcam.html

Dundas the falcon does it again

By Eric McGuinness
The Hamilton Spectator
(May 15, 2007)
Losing a leg is proving no disability to Dundas, a peregrine falcon born on the Hamilton Sheraton Hotel three years ago.

He's managed to not only survive but to attract a female and fertilize four eggs his unidentified mate is incubating on the north tower of the Burlington Canal lift bridge.

"He has beaten the odds," says Mark Nash, executive director of the Canadian Peregrine Foundation.

"He has proven me wrong again and again. I said he wouldn't survive after losing his leg. He did. I said he wouldn't survive his second winter. He did. I said he would never attract a mate. He did. I said he wouldn't be able to copulate and fertilize an egg. He did. I now have my fifth shoe in my mouth."

The female at the Burlington nest site, believed to be from Pennsylvania, produced four eggs last year with another male, but three didn't hatch and the one chick soon died.

Based on when the first of this year's eggs was spotted, the first hatch is expected in 10 to 12 days.

Meanwhile, Madame X and a male presumed to be Surge, the male who mated with her last year, have a brood of four chicks at the Hamilton Sheraton.

The final appearance was confirmed Sunday when Madame X moved enough to let the falcon cam (www.hamiltonnature.org/hamfalcam.html) catch a good view of all four.

Dundas, born in the spring of 2004, was spotted with a leg missing that fall, and experts thought he was doomed because falcons normally need both feet to mate, defend territory and hunt.

But Dundas roosted on the Old Navy sign at Lime Ridge Mall where he learned to chase pigeons into the glass, then balance on one foot to tear them into bite-sized pieces.

He eventually moved to Kitchener where he set up housekeeping on the Royal Bank of Canada tower with a female from Ohio last spring, but they didn't produce any young and he didn't stay around.

Birders reported three falcons around the lift bridge this year, with some serious territorial squabbling in which Dundas apparently drove off last year's male.

The new pair ignored a nest box installed on the south tower last year, and by the time the foundation installed one on the north tower this year, the female had already decided to settle again for an exposed steel beam for her scrape, as falcon nest sites are known.

I had a question today from a woodward ave resident, when do they get fed?
The falcons eat whenever they feel like it, there are thousands of tasty pigeons living on or near the Lift Bridge and the slow ones don't last long. They do seem busier around sunset and sunrise. So, no one feeds them (if that is what the resident meant), they feed themselves.

Burlington Nest site update - June 2nd -2007

It is with great sadness that given the current late date, and the adults recent behavior, that it would appear that the Burlington Bridge nest site has failed this year. Now more than a week after the expected hatch date, and upwards of 40 days of incubation, it would appear that a hatch is not going to happen this season, (at least with this 1st clutch of eggs).



While there is always hope that we are way off in the starting of the “full time” incubation time frame of the female, we don’t believe so.

A many number of things could have gone wrong, not to exclude Dundas’s inability to properly mount the female for successful copulation / fertilization??? We had discussed this very same subject in great detail several months ago when Dundas arrived on territory and displaced the existing territorial male from this nest site.



While it is very possible for the female to produce a second clutch of eggs, Dundas must successfully copulate with the female and fertilization must take place for the any of the eggs to hatch.



Also, the female is unlikely to produce a second clutch of eggs (at least at this very same spot) until the first clutch of eggs have been consumed. Who knows, maybe they might try the nest box next??? In any case, the adults have been observed copulating again, and it appears that the female is at least receptive to his Dundas’s advances!



Maybe having only one leg will really be his nemesis!!!

Stay tuned, as we will continue to watch closely for any new developments…………….



Sincerely

Mark Nash
