Buenos Aires, Argentina (4) (1 Viewer)

opisska · Mar 10, 2014

So being in Argentina for the 9th already, I think I started to get a grip on most of the commoner birds and I have bravely IDed almost 60 species so far this trip myself. But there are still unknowns for me.

All from Reserva Costanera Sur, a swampy park in the centre of Buenos Aires, a couple of fays ago:

1 - I call this for a lack of better idea a "palm tanager" but it has no wing pattern and really no business down south

2 - female of some seedeater? the females are not all illustrated in my book

3 - is this a 1234th version of Variable Hawk I haven't seen yet?

4 - just a long shot for a hummingbird, very difficult folk to take picture of, probably not IDable.

Thanks in advance!

Re 3: Variable hawk usually has a thin black band on a mostly white tail while this one has dark tail with pale undertail coverts. I have a feeling I should know this one but nothing pops up.

Edit: Snail Kite female? Not sure though

Thanks! According to my book I have here (Erize-Mata) it doesn't fit well, it's kind of male-female crossover, but some pictures on the internet provide much better fit, there is apparently some variability in head color. Also, the habitat is very suitable.

I have just gotten paranoid with varibale hawks as like 9 out of 10 strange birds of prey I see around Malargue turn out as one of those tricky creatures, but this is Buenos Aires, where they are much less common, so I should have considered that.

Snail kite seems good for #3.

For #1 I'm seeing some pale blue feathers on the rump. How about blue-grey, sayaca, or whichever of the bluish Thraupis tanagers occurs in BA?

Not going near female seedeaters 8-P

Severe backlighting on the raptor is a bit of a problem, but with dark body, chestnut underwing coverts, white undertail and mostly black tail with a white tip why not Harris's/Bay-winged Hawk? That's waht I'd have it down as if I were in the area (which I may be later this year, fingers crossed, hence my interest in this thread).

The Harris's Hawk I remember seeing from Chile looked a lot more like http://www.birdforum.net/gallery/showphoto.php?photo=361333 -- if this bird is a Harris it looks a lot more like the N American versions of it. I did not know there was so much variation of this species in S America. Zooming in, I can see the chestnut on underwing, and Harris's would fit better with the shape of bill (which I excused as a funny angle effect).

1 looks like Young Sayaca Tanager
2 female Seedeater most probably Double-collared S.
3 Bay-winged Hawk. I have seen same not 1 month ago in Costanera Sur.
4 female Glittering-bellied Emerald

Hi Niels, that photo looks like a young Harri's Hawk.

Thanks (and to everyone else as well, of course)! 1 is really Sayaca? That's funny how non-blue it can be! At least I wasn't wrong calling it a tanager!

ad 2: double-collared males were very numerous in Costanera, so I guess that's quite reasonable.

ad 3: it's funny when you can get an ID not just on a species, but on an individual bird

I saw 3-4 birds in central Chile, and my memory is that the guide called two of them adults. I was surprised by the difference between the birds and those I had seen in the US not too long before, that is why my memories of these are quite vivid.
