Hi,

I saw these birds at approximately this location around February 5th:
https://www.google.com/maps/place/10°30'22.7"N+84°42'00.7"W

Pictures 1-2: Dusky Antbird?
Pictures 3-4: Some sort of Tyrant Flycatcher?
Picture 5:
Picture 6: probably unidentifiable...

Thanks!

Picture 6

1-2 is ochre-bellied fly (not pink base to bill)

3-4 looks very much like Yellow Tyrannulet.

I might be completely wrong but 5 have some similarity to a barred becard female

I see where you're coming from but I don't think it's that. We should see a clearer transition from crown to nape and s bigger more uniform rufous wrong panel I think

[Edit] I thought it might be olive-striped fly but I'm not wholly convinced of this either

This is an image of a bird eventually identified as Barred Becard: https://www.birdforum.net/opus/Image:5_Flycatcher_P1060073.jpg

Hmm. Perhaps you're right!

Picture 6

Best guess is tawny-crowned greenlet but I'm not completely convinced. Do you have other photos?

Unfortunately not.

Thanks all for the help :t:

Elevation is about 500m I think. So, would be unlikely I think there. How about White-winged Becard? looks pretty close to me.

could be Ochre-bellied again.

Possibly: I thought the bill looked wrong (too thin), but who knows?

The images I can find of a female are from south America and show a mantle that is too rufous compared to yours. However, did you find any images that are within the region?

Yes I agree. if we're sticking with the female becard theory, female black and white is a better bet. Ebird suggests there are records from that part of CR [I only looked at the coarse resolution map, though]

njlarsen · Mar 22, 2020

The better map is here https://ebird.org/caribbean/map/baw...mr=1-12&bmo=1&emo=12&yr=all&byr=1900&eyr=2020

There is a single observation from the Arenal observatory, and significantly more from Monteverde on the other side of the mountains.

I agree this one looks better.

Range map of white-winged shows far more records in the area... https://ebird.org/caribbean/map/whw...mr=1-12&bmo=1&emo=12&yr=all&byr=1900&eyr=2020

Here are images of females in CR: https://ebird.org/media/catalog?tax...CR)&regionCode=CR&sex=f&q=White-winged Becard

The second image here doesn't show much rufous as far as I can see... https://ebird.org/species/whwbec1

Your record, your choice, but those images show a brown/rufous mantle or mantle patch which your image doesn't have. I'm talking about the area on the "shoulder" just above the folded wing. This is clear on the ebird headline image (last link). It's sometimes unclear or invisible on the other images but in those cases we can tell it's due to lighting: the lighting on your images is good and helps us tell your bird is olive there

njlarsen · Mar 23, 2020

I am with the Fern here. I think that the danger of ebird is that sometimes, semi rare observations get changed (wrongly) into the more common species. I would make an ebird report and upload the picture as evidence to see what the local reviewer feels about it.

Alright. Thank you both for the help
