A very co-operative young bird at Downsview Park.

Nice photos of an adorable bird. It was also nice meeting you two. Afterwards we went to see the RTH; by then he was out hunting. Then on Sunday afternoon we saw him grabbing a toad and swallowing it whole. While the heron in Downsview is swallowing mouse, I guess the RTH stared liking amphibians - a bit lop sided it seems.

Good one John.

I was there yesterday and unfortunately someone has traumatized him.

Tags on both legs which he kept looking at and no longer the trusting guy he used to be. First sight of people and off he went.

Must have happened between the time you took the shot and the 2nd.

He used to provide lots of enjoyment to many people - park users, joggers, cyclists, seniors and kids.  Some would even take pics with cell phones. Others stood in awe watching him hunt and eat. People never bothered or harassed him in any way and the few photographers there now and then always kept their distance.

But... for whatever reason they baited, netted and gave another bird a lesson on the cruelty of the human race!

For what purpose except wasting more of our dollars ???

I have never ever seen anyone with scopes or binoculars looking out at the birds there. So whoever did this, shame on you!

I shiver to think of the discomfort the bird will have with a metal ring around its leg at -10C in Downsview park. Banding is a good way to study Bird's migration pattern, not sure what a resident hawk will reveal at the end - probably a good intention gone awry.

That is assuming this and the other residents at DV do migrate.

This one was tagged after it had reached "almost adult".

What is not acceptable is the large plastic tag that covers the entire lower leg. Now he cannot preen those leg feathers. He cannot pick off bugs and insects that might climb up that leg etc.

Frankly, I’m a bit shocked at some of the vehemence and misinformation concerning banding being expressed here.

There are actually two different Red-tailed Hawks at that location, and both were banded with stainless steel federal bands and coded colour bands last week as part of an ongoing project on winter site use and fidelity. I have gone to see these birds since they were banded and they are just as approachable as before, hardly “traumatized,” but rather hunting and making successful kills just as they should be. I saw one of them perched up in a tree and it was not disturbed when I walked up to the trunk - it looked and went back to preening itself. Regardless, I wouldn’t be so quick to assume that it’s a good thing for a wild bird of prey to allow people to take photos with their cell phones - wildlife and raptors specifically still face plenty of persecution, and an animal that doesn’t learn to be wary of people may well end up dead, so I hope for their sakes that these birds do in the long run.

I don’t know how much you know about the bird banding program, but none of your money was involved - banders supply their own equipment and are generally not paid for what they do unless they work with MNR with waterfowl or at a migration observatory, which even then is for the most part volunteer except for the bander-in-charge.

Bird banding is not just about migration, and there is just as much to be learned about local birds (which at this point we don’t even know if these birds are local, resident, or migratory - up until this point it was assumed that there was only ever one bird, when in fact there are two using the same fields). Without being able to recognize individual birds there is no way to say for certain whether the same bird overwinters or if there is turnover and they are replaced by new birds moving in, and furthermore if these same birds return to the same site next winter, or even if they return and attempt to nest as adults. Otherwise it is simply speculation. There are more birders who visit Downsview than you think - so yes, shame on me for taking the opportunity to gain insight into the habits of these urban hawks, which are surprisingly quite unstudied here.

Also, these birds are not “almost adults” - both were hatched this year and will not attain adult plumage until next summer. Red-tailed Hawks do not have feathers on their tarsi (and many species that do such as owls and Rough-legged Hawks are banded regularly with no ill effects), and the bands will have no impact on preening whatsoever. Waterfowl, gulls, and other species that spend a good part of the year in near freezing water or roosting on ice are banded and colour marked by the thousands - far harsher than any conditions a bird of prey will face in Toronto. The birds' legs were gauged and the appropriate diameter bands were used - I've banded close to ten thousands birds and have worked with many birds of prey, and all protocol and permits were in place.

I don't mean to derail John's thread, but I needed to step in here. You're welcome to contact me in private or I can get you in touch with the bander leading the project.

Sorry to continue to drag this off topic, but I feel that topics ought to be allowed to take their own course...human discussions often get derailed and no harm (in fact sometimes much good) comes out of it.  

Downsview is definitely a park that's in danger of being bulldozed over for more housing/condo projects.  So if these banding studies help in any way to delay or reduce or eliminate altogether these projects, then I'm all for them.  

The wildlife at Downsview is remarkably diverse for a park so open and in such an urban location.  It's a jewel in our city that we can't allow to disappear.

I agree; a passionate discussion about the welfare of birds and animals in general is healthy. May be this is not the right forum; however let the discussion continue.

I am very well be misinformed about bird banding; however, I am finding it hard to agree with the statement that feathered made about "many species that are banded regularly with no ill-effects". Well, how could one come to the conclusion like that when only 5% of all banded birds are ever tracked? The number goes below 1% for song birds. Am I reading it wrong? 10,000 banding is a nice sample size - I wonder what percentage of that was ever tracked?

I did some on-line research and found a few articles published in peer-review journals that say to the contrary - as a result of banding the mortality rate goes up anywhere between 2% to 33% depending on the species. There may be different view points.

.........Red-tailed Hawks do not have feathers on their tarsi .....
Does anybody have the answer to the question as to why? Why did evolution leave that space blank? I don't think it was for us to put a band around that area. Go figure.

Anyway, I would certainly like to learn more about these banded birds - can someone please PM me the band numbers? I visit Downsview quite regularly, I would love to see how their story unfolds.

I assure those concerned with leg bands and the chill in Canada that the bands will not make the bird uncomfortable or have its legs fall off. See any one legged Peregrines about the city?  

As for tracking, well I'm no expert, but some people who chance upon a dead banded bird call in the band # which is a form of tracking.  Sure there probably aren't many called in compared to never seen or reported again.  But there are re-traps also at banding labs and some times it can be a few years passed from one trapping of the bird to another.  I recall reading up on a Yellow Warbler that was re-trapped and the bird was at least 11 yrs old if my recollection of the story is correct.  It was the oldest known Warbler.  We follow the Ruthven bird banding lab blog and they occasionally post about some interesting re-traps.  

I've had a few banded birds come to my feeders in the last year and a bit.  Many hours and hundreds upon hundreds of photos of those bands had me successfully piece their I D #'s, allowing me to report the birds to the bird banding office of Canada. They rarely get someone from the GP calling in to report LIVE banded birds.  There has been some excitement with my calls.  

First bird was a female Gold Finch banded in Prince Edward County, almost 300 kms east of my home 5 years prior to encounter report.  Second bird, a male Baltimore Oriole, showed up at the same time, and I only got a partial before fall migration last year.  He returned this past Spring to my joy and surprise, and I finally got his full number.  That bird was banded in Long Point in 2012.  

We happened to make it to the Prince Edward banding lab last fall and I was able to share my story of the Finch. And someone I know, knows the bander of my Oriole and was thrilled to tell him about it.  

Sorry for the stories but I wanted to shed some positive light back on this thread as well.

A birth certificate shows we were born.  A death certificate shows we died.  Pictures show we live.
