A swift In Costa Rica (1 Viewer)

[Stan95100]

In Costa Rica in February, from the top of the observation tower of the Wilson Botanical Garden (Estación Biológica Las Cruces).

A swift presented as a "Vaux" by the French-speaking and local guides.

A confirmation or not, would be welcome.

With thanks.

Avec mes remerciements.

Not sure you can decide between Vaux's and Costa Rican swift based on this image alone. Perhaps "feels" a bit more like the latter for me, but only based on comparisons with Ebird pictures.

The field guide states that in Vaux, the throat is clearly paler than the lower underparts. That is not possible to judge based on this image I think. Ebird looks like maybe 2-3 times more Vaux than CR Swift at the location?

Looking at the ebird images for both species, I feel we should be able to see a clearly visibly paler throat here (for either species). We can't see that at all—at best it's extremely marginally paler. Of the 2 options, though, the images of Vaux's seem to me to have the more obvious and extended pale patch and so are less likely to have been this bird. But an image of the rump is really what we want.

Hello everyone and thank you for your answers. The birds were flying too high so I don't have better photos.

Cordially.

Bonjour à tous et merci pour vos réponses.

Les oiseaux volaient trop haut et je n'ai donc pas de meilleurs photos.

cordialement.

For the gray of the throat.

The same bird if it can help with an identification ^^

Pour le gris de la gorge .

Le même oiseau si ça peut aider à une identification^^

My comments are as before. But please have a look at the ebird photos to see what you think:

Again, rump photo needed to be sure afaik

Hello THE_FERN and thanks for the links, really.

The photos are without comparison with mine, and I do not find on the birds that I photographed, the gray of the rump of "Costa Rica".

Thanks again for the link to this site.

Cordially.

Bonjour THE_FERN et merci pour les liens, vraiment.

Les photos sont sans comparaison avec les miennes, et je ne retrouve pas sur les oiseaux que j’ai photographiés, le gris du croupion du « Costa Rica ».

Encore merci pour le lien vers ce site.

Cordialement.

Salutations depuis le Costa Rica. J'ai revu ta photo et par le nombre de plumes pointues deux contre 4 ou plus à Vaux c'est une forme d'identification. Bien sûr, la forme des ailes et la partie sombre sous ce qui serait les tectrices primaires sont également essentielles.
J'espère que vous pouvez comprendre mon français, je n'ai pas écrit depuis longtemps.

Thanks. Fine to write in French but please also supply an English translation (BirdForum "speaks" English). Here I see you're referring to the number of tail spines as an id feature. There seem to be 2 which should make it Costa Rican (cf Vaux's 4+)

Greetings from Costa Rica. I saw your photo and the number of pointed feathers two against 4 or more in Vaux is a form of identification. Of course, the shape of the wings and the dark part under what would be the primary coverts are also essential.
