Doubts with Brazilian birds (1 Viewer)

Hi all,

I'm just back from a trip along south Mato Grosso do Sul (MS) state (+ far east Paraguay) and Iguaçú NP (Brazil + Argentina). Here are some birds I'm having difficulties to ID, and with which I'd appreciate help:

1 - Immature Roadside Hawk (Rupornis magnirostris)? Eldorado, MS, Brazil.
2 - Mystery bird is near the centre, under the male Double-collared Seedeater (Sporophila caerulescens). Lots of the latter around, but no idea on the ID of that mystery one. Jacareí, MS, Brazil.
3 & 4 - I'm guessing either Xiphocolaptes albicollis or Dendrocolaptes platyrostris. Is it IDable? Salto del Guairá, Canindeyú, Paraguay.
5 - Another horrible photo, but is it possible to ID? Iguazú NP, Misiones, Argentina, antropic area.

http://jocateme.multiply.com/photos/album/35/35#18 - Iguaçú NP, Paraná, Brazil.

http://jocateme.multiply.com/photos/album/35/35#22 - Same place. Is this Leptotila sp. IDable?

http://jocateme.multiply.com/photos/album/35/35#27 - Same place. I remember having seen a white supercilium in that bird, but now I'm not so sure about that mark.

http://jocateme.multiply.com/photos/album/35/35#28 - Any possible ID by jizz?

http://jocateme.multiply.com/photos/album/35/35#45 - Phylidor lichtensteini?

Thanks.

On bird #5 I agree with Phylidor lichtensteini , the underside is too yellow for Buff-fronted. Excellent Bird !!

Nice mystery photos!
The Hawk looks like Imm. Roadside with its combination of streaks on chest and barring below.
The Woodcreeper silhouette does look like Scaled (or at least a Lepidocolaptes with that thin decurved bill).
Reddish bird is probably Red-crowned Ant Tanager.
Flycatcher- maybe a Phylloscartes sp.?

The rest- cant say for sure.

Thanks Patrick and Stephen!
Think I should confirm Red-crowned Ant Tanager, then. Some friends suggested it as well.
I haven't found photos of Phylidor lichtensteini on the net for comparison, thus my doubt about the ID. But the mark you said leaves us with no other options, I guess. Thanks!
Patrick, you mean the woodcreeper on bunch #2, right?
The flycatcher might be a real problem. I have numerous doubts on IDing them with good photos, let alone with this horrible one! Silhouette really seems good for Phylloscartes, though.

Thanks again, Stephen and Patrick!
