Confirmation of 2 large vireos in Colombia (1 Viewer)

[Valéry Schollaert]

Hi guys,

I've seen what looks like a regular Black-whiskered Vireo to me, in Girón (Santander), Colombia, end of August. I'm just surprised to see this wintering species that early and would feel more confortable if someone can confirm there's no other species with such malar stripes.

The other photo was taken this morning in an urban park of Bucaramanga (Santander, Colombia). Last time I was in South America, Chivi Vireo was a subspecies of Red-eyed Vireo. I didn't watch them enough... my bad. Now, I found online that there's a difference in the wing formula. I would conclude my bird is a migrant Red-eyed Vireo and not the local Chivi Vireo. Am I right ?

Thanks.

Probably... On my phone so I can't tell what colour eye the chivi/red-eyed video has (brown vs red). The bird looks quite dull which apparently suits red-eyed better.

Other does look like black-whiskered

The BwVi looks good to my eyes. There is an observation in Santander in the third week of August according to the bar chart:

Thank you both, I hope I'll manage to learn more about Chivi Vireo.

Agree with others that he first one is Black-whiskered.

The situation with Chivi is complicated by the fact that there are also Austral migrants in Colombia from April-August and these have somewhat primary projection (tip of wing past longest tertial/secondary). It would be great if you shared any more photos you might have of this bird to get a better idea of the actual primary projection. When the wing is held slightly "drooped" like this (tertials not in line with primaries) the wing primary projection always looks a little longer than in realty it may be. In favour of Chivi is the fact that the eye is not red and the date is on the early side for Red-eyed in Colombia.

Wing formula favours red-eyed according to the Todd paper suggest

I think my bird is a 1cy, hence the dull eye. I grouped the question the Black-whiskered Vireo because it seems to me that, if BwV is already there, ReV coming from farther North and going farther South has all chances to be there too. Usually, long distance migrants start their journey earlier.
I've no other pics of this individual, it stay hardly a second in view.

Today, I came back in the same parc (Parque del Bosque Encantado).

I've seen this one, I guess an adult ReV. Again, it was very elusive and don't have any other pic. I'm staying 6 to 8 weeks in Bucaramanga so I will hopefully see many more and learn about their identification.

This one appears to have a red eye—at least on this monitor. If you have access to image manipulation software [photoshop, gimp etc] worth playing with curves to see what the "underlying" eye colour is.

indeed, I've no doubt about being a Red-eyed, confirming it is in the park. I was replying to Avery who considered the date early for ReV.
