Most birders don’t visit Costa Rica to look at shorebirds. Their rung on the birding priority ladder is outpaced by endemics and hundreds of other species not possible at the home patch. Even so, sandpipers and plovers are always fun to watch and if you get a chance to do some shorebirding in Costa Rica, you’ll reap the following benefits:
Lots of Birds
Bird in Costa Rica in the right places and you might hit a wader jackpot. Thousands of shorebirds migrate through and winter in Costa Rica, much more than we manage to document. As I write, I’m sure that fantastic flocks of sandpipers and plovers are moving along both coasts. Some birds stop, many fly on and pass through Costa Rica’s bit of air space in less than a day. Among those migrating groups of birds, among the birds that stop to rest and others that continue on, a rarity or two could certainly be present.
Marbled Godwits, Surfbirds, and Wilson’s Plovers
Birders who aren’t from this side of the globe will get their fill of Western Hemisphere waders. Yellowlegs, Willets, “Hudsonian” Whimbrels, Western, Semipalmated, Least, and Stilt Sandpipers, and more. Among some of the more interesting and wanted shorebirds are Marbled Godwit, Surfbird, and Wilson’s Plover, lot’s of Wilson’s Plovers!
Find a Siberian Vagrant
As with other places that concentrate shorebirds, Costa Rica can also host vagrants from Siberia. So far, such lost shorebirds have taken the form of Ruff, Curlew Sandpiper, and Pacific Golden-Plover but given Costa Rica’s position on the Pacific Coast flyway, more are certainly possible. I’m sure a few of those species have been here but passed through unseen or unnoticed. Four species of stints are possible, the most likely ones maybe being Red-throated and Little Stints, the others being Little, Temminck’s, and Long-toed Stints. Sharp-tailed Sandpiper is also likely (one was seen in Panama), and Lesser Sand Plover and Bar-tailed Godwit could also make a surprise appearance.
Yeah, real long shots but all are long distance migrants that migrate through or too similar latitudes in southern Asia and all have occurred in Washington state or California. Some have probably made it to Costa Rica at some point, hopefully a few will make it here again. It doesn’t hurt to be ready to recognize them (and is why these and other possible vagrants are included on the Costa Rica Birds Field Guide app). Unfortunately, separating winter-plumaged Red-necked and Little Stints from Semipalmated Sandpipers is an incredible challenge. If you see any funny looking Semis in Costa Rica, take a closer look and take a lot of pictures.
Much More than Shorebirds
A befits the bird-heavy nation of Costa Rica, one of the other benefits of watching shorebirds is seeing lots of other birds too. As one might expect, various other waterbirds will also be present, often, birds like Roseate Spoonbill and White Ibis. On the Pacific Coast, there will also be a fair selection of dry forest species and mangrove birds including chances at uncommon species like Rufous-necked Wood-Rail, Mangrove Rail, and Mangrove Hummingbird.
Provide Important Data on Wintering and Migrant Species
As with all birds, keeping them around depends on knowing how many occur and where they make a living. Taking a day or two to focus on shorebirds, making careful counts and then uploading the data to eBird is an easy way to help.
It’s always worth it to watch shorebirds. In addition to helping with eBird data, in Costa Rica, a scopeful of elegant migrants from the far north can act as a relaxing break from the challenges of forest birding.
