Crested Oropendola

Crested Oropendola: Las Cruces Biological Station, OTS, San Vito, Costa Rica, December 2022 — Our first morning at the Las Cruces Biological Station, which is owned and managed by the Organization for Tropical Studies, we gathered on the deck behind the dinning hall and put out a few bananas for the birds. The sun was not fully on the deck yet when a pair of Crested Oropendolas came in. The Crested Oropendola has an extensive range in South America, pretty much at the mid-elevations surrounding the whole Amazon Basin, but it only reaches as far north in Central America as the border between Panama and Costa Rica…just into Costa Rica in the extreme south west. I had distant views of the bird in 2021 from the same deck at Wilson Botanical Gardens at Las Cruces, but this was my first close view. Wile not as large as the Montezuma Oropendola, it is still an impressive bird. A member of the Oriole family. The Las Cruces station is one of 3 in Costa Rica dedicated to providing habitat and housing for tropical research. OTS acquired the Wilson Botanical Gardens, formerly a commercial garden, when the Wilson’s retired. At least a good portion of there support these days comes from hosting birding and photography groups like ours in the rooms they provide for students. It is always a privilege to visit.

Snowy-bellied Hummingbird

Snowy-bellied Hummingbird: Las Cruses Biological Station / Wilson Botanical Gardens, Costa Rica, December 2022 — Not the best photo but a very good bird. We missed it yesterday…at least missed photo ops…so I was out at sun-up in the gardens waiting for it this morning and it came just as I would have had to leave to make it back for breakfast. One quick stop in the sun and it was gone again. Sony Rx10iv at 600mm equivalent. Program mode with my custom birds and wildlife modifications. Processed in Pixelmator Photo and Apple Photos.

Golden-hooded Tanager

Golden-hooded Tanager: Wilson Botanical Gardens, Las Cruses Biological Station, Costa Rica, December 2022 — One of my favorite Tanagers of Central America…especially when seen in good early morning light. Found on both slopes from lowlands through foothills. Sony Rx10iv at 591mm. Program mode with my custom birds and wildlife modifications. Processed in Pixelmator Photo and Apple Photos. ISO 100 @ f4 @ 1/800th.

Buff-throated Saltator

Buff-throated Saltator: Las Cruces Biological Research Station (OTS), San Vito, Costa Rica, December 2021 — The Buff-throated Saltator is one of the most common birds around feeding stations in Costa Rica, on both the Caribbean and Pacific slopes…from the lowlands well up into the foothills…so not so exciting to see it at Las Cruces, but still a good bird 🙂 Sony Rx10iv at 591mm equivalent. Program mode with wildlife modifications and multi-frame noise reduction. Processed in Pixelmator Photo and Apple Photos. Equivalent ISO 2500 @ f4 @ 1/500th.

Fiery-billed Aracari: my best side?

Fiery-billed Aracari: Las Cruces Biological Research Station (OTS), San Vito, Costa Rica — Another visit from the Fiery-billed Aracaris. This bird seemed to want to show us every side. Aracaris are active birds…never still…always hopping around on the branch. And they are very focused…intent on food mostly…but also very aware of the other birds of the flock.

Female Scarlet-rumped Tanager (with bonus bird)

Scarlet-rumped Tanager (female) and Golden-hooded Tanager, Las Cruces Biological Research Station, San Vito, Costa Rica, December 2021 — I mentioned that the Passerini’s and Cherrie’s Tanagers were considered separate species, each with an isolated range on either cost of Costa Rica (no overlaps)…at least for a while. They were once considered the same species, named Scarlet-rumped Tanager…and then the AOU (the bird naming committee) decided they were different, based on range, and on the obvious differences in the plumage of the females (the males are identical), but recently ornithologist have come up with a new method to study species, called the “playback method”. They play recorded songs and calls of an apparently closely related species, to determine if the birds under study respond as they do to their own calls and songs. In the case of Passerini’s and Cherrie’s Tanagers, both respond equally as well to the other’s songs and calls…making it very likely that they are the same species, or at least that they would interbreed if their ranges overlapped. This inspired genetic studies to follow up…and indeed they appear to be the same species, just separated by a mountain range. The Golden-hooded Tanager just had to get into the photo.

Blue-headed Parrot

Blue-headed Parrot: Las Cruces Biological Research Station, San Vito, Costa Rica, December 2021 — It really is amazing how many different parrot species we saw at the Wilson Botanical Gardens at Las Cruces. What is more amazing, is the we were seeing so many good birds that no one really remarked on the number of parrots 🙂 This is the Blue-headed Parrot…for obvious reasons…terrible lighting, and way too far away, but still great to see. These took special effort in post-processing 🙂 Sony Rx10iv at 600mm equivalent. Program mode with my custom birds and wildlife modifications. Processed in Pixelmator Photo and Apple Photos. ISO 200 @ f4 @ 1/500th. +2EV exposure compensation for the strong backlight (and then a lot of pumping up and black-point adjustment, as well as deep cropping and enlargement, in post).

More action over papaya

Golden-crowned Euphonia (male and female), Scarlet-rumped Tanager: Las Cruces Biological Research Station (OTS), San Vito, Costa Rica, December 2021 — The male Golden-crowned Euphonia seems to think the papaya rind belongs to him and his mate, while the Scarlet-rumped Tanager begs to differ. I will probably share more on this in another post, but the Scarlet-rumped Tanager was considered two species until recently, Passerini’s on the Caribbean slope and Cherrie’s on the Pacific. This would be a Cherrie’s. Sony Rx10iv at 591mm equivalent. Program mode with wildlife modifications and multi-frame noise reduction. Processed in Pixelmator Photo and Apple Photos.

Meeting over papaya

Speckled and Silver-throated Tanagers: Las Cruces Biological Station, San Vito, Costa Rica, December 2021 — I don’t often post photos of birds actually at the feeder, but sometimes the interactions of contrasting species that take place there are just too good to pass up. Both of these birds are common in mixed feeding flocks at the right elevations in Costa Rica (the Silver-throated is common everywhere in Costa Rica…I think it might cover the widest range in elevation of any Central American Tanager) so it is no surprise to see them together at the feeding station, but for those of who only visit Costa Rica once a year, it is still a rare treat.

Specked Tanager

Speckled Tanager: Las Cruces Biological Research Station (OTS), San Vito, Costa Rica — I have shared this bird before, but not this photo, which is arguably the best of my Speckle Tanager shots from our visit to the Wilson Botanical Gardens and Las Cruces. Such an amazing bird! They are listed in my field guides as “common”, and often included in mixed feeding flocks, so relatively easy to see…if you happen to be in the foothills and mid-elevations of Costa Rica or Panama, or in scattered regions in northern South America…so not so common for most of us.
