A June Mangrove Cuckoo [confirmed by the experts.]


This photo was taken by José Carlos García near the Río Mono bridge in Bayano, sometime in June. The bird was identified as a Mangrove Cuckoo, which, though rare during the boreal summer, has been reported in Central Panama in June. As fas as I know, there are no records of over-summering Yellow-billeds in Panama, and the yellow bill seems to rule out all those southern vagrants, but if you have any better guesses do chime in.

Pearly-breasted Cuckoo(Coccyzus euleri)may be a better candidate for this bird. Pearly-breasted Cuckoo is an austral migrant that looks more or less like a Yellow-billed Cuckoo but with no rufous in the wings and gray eye ring instead of yellow. Although the eye ring is hard to see, there is no indication of yellow in this image. The bird in the image also shows light gray on the throat lacking the buff tones of Mangrove. Upperparts also look to be darker brown than the grayish brown of Mangrove.

The plot thickens. Pearly-breasted would be a new species for Panama (and thus for the AOU area), so erring on the side of caution would be advisable. I'll re-circulate this among the experts to see if they've changed their mind in these two years.
thanks!
