The big yellow patch is what indicates that it is a male, while the female has only the brown spot on each wing. The feature photo is one typical view with a greenish/yellowish hew on the folded wings while the top of wings are usually a bright white like the photo below where the same butterfly is strangely contorted. See more of my photos of this interesting butterfly in my gallery: White Angled-Sulphur, Anteos clorinde. They are found as residents from Argentina to Mexico with migrants going into the Southwestern U.S. and Great Plains.
He’s becoming a favorite among the flowers and not sure he comes to the feeders that are dominated by the Rufous-tailed. See more photos from this week in the GALLERY: Blue-vented Hummingbird.

This is one that I have constantly confused with the Thoas Swallowtail with very little, tiny differences. But I think I have this one identified correctly this time. 🙂 From my garden and of course there is a GALLERY: Western Giant Swallowtail.
When I look at only the head, I think this is a Black Vulture, but the arrangement of white feathers (in shadows) on the wings show that it is a Turkey Vulture and the lack of a red head, makes it a juvenile. Vultures fly overhead regularly, helping to keep the neighborhood clean. 🙂 And they make flying look so easy and graceful that I can’t stop trying to photograph them, even though seldom a good photo with shadows and movement, but fun anyway! 🙂 And my Turkey Vulture Gallery of course!

“The Clay-colored Thrush in Costa Rica eats a varied diet of insects, earthworms, and other invertebrates, supplemented by fruits and berries. They are found in diverse habitats across the country, including forests, open woodlands, gardens, and urban areas. They forage primarily on the ground by hopping and probing leaf litter, but also eat fruit from trees.” ~Google AI Overview. See more photos in my Gallery Clay-colored Thrush.
The adult males are a strong black & blue while the adult females are brown. It is the immature males that have the mottled brown, blue & black look like this. See more photos in my Blue-black Grassquit Gallery. Including my favorite shot of females lined up on a barbwire fence at Carate adjacent Corcovado National Park back in 2009 on my first trip to Costa Rica. 🙂

A tiny little creature who stays close to the ground and on ground cover flowers like this. Not my first sighting, but first one this year. Formerly called Tulcis Crescent; see more photos in the Gallery: Pale-banded Crescent, Anthanassa tulcis.

In the past two years this was seen more often than this year for some reason. It was frequently near the ground or on grasses and ground-cover, but this time in October mostly on my Lantana flowers. It is very small, about the size of my thumbnail when his wings are folded. See more of my photos in the GALLERY: Hermes Satyr. This species is almost identical to another one found in the U.S. called Carolina Satyr, which is what I first labeled these guys here, but all indications are that here in Central America they are called Hermes and considered a different species. Here’s two shots from my garden . . .
It looks bluer in person than in the photos and the male is solid blue on top of wings, while the female is solid brown on top. This one is my first “blue” this year, I think. I found him on the yellow ground-cover flowers on my side of the driveway slope, where I have to use my walking stick (trekking pole) and good sports sandals or hiking shoes to hold me on the very steep slope while photographing. 🙂 Some species only go to certain flowers when available, so maybe I will start checking these flowers more often. 🙂 We are entering the “fewer butterflies season” for my garden until it picks up again next April/May, though there are some butterflies year around, just like the birds! See more photos of this species in my GALLERY: Eastern Tailed-Blue (including some blue tops). You will find more of these in the Eastern half of the U.S. and Canada than here, but this “northern butterfly” does range as far south as Costa Rica. We get them from both North & South America! 🙂 Here’s two shots from an October sighting . . .
