Tarcoles River Costa Rica

The 16th February 2020 saw Reagan and I on the Tarcoles River in Costa Rica. We were on the river at 9:30am which isn't bad for a tour off a cruise boat but perhaps a little late for the best birding. Most people were excited to see the crocodiles but it was the birds I was keen on of course.

Photography from a boat with a P900 is an exercise in frustration with a much higher rate of blurred images than normal. There is only so much that motion compensation can do with 2000mm of zoom and a slow focus system but I just went shutter crazy and took as many photos as I could. The boats were a sort of triple long BBQ barge so reasonably steady but we never really came to a stop.

My ebird record shows 32 species but not that many usable photos. There were scarlet macaws flying overhead but they didn't settle where I could get a photo.

The first two birds we saw didn't have their breeding plumage which is a shame because I would have liked to photograph the spots on the spotted sandpiper. The neotropic cormorant didn't have the white stripe behind the orange facial skin so could have been a juvenile.

The highlight of the trip was seeing a bunch of Egrets and Herons including the Tricolored Heron and the Little Blue Heron whose photos didn't make the cut.

The Roseate Spoonbill was hiding but the colour is still gorgeous.

A pair of Magnificent Frigate birds were posing on a perch which seemed a surprising place for them on the river but in truth we motored past the river mouth so they weren't that far from their usual coastal haunts. The predator is a Common Black Hawk.

The small lizard is a Common Baslisk. You can tell it's a male by the head crest. It also has a crest on its back and long tail. Nicknamed the Jesus lizard, juvenile Basilisks can run over water up to 20m to escape predators. The Bigger lizard is a crocodile.

I don't know what sort of Bats are in the photo below. They are tiny and look just like lichen on the underside of a log.
