Costa Rica Birding News, October, 2023

October. It’s the threshold of winter, Halloween, and pumpkins (with all of their orange colored spice). By the cool breeze from the north and the slowing down of deciduous trees, the birds know the deal is up. They know it’s past time to have fattened up and made the journey south. Indeed, up north, most of the first migrants have already paid heed to instincts and fled to the tropics. Thrushes, warblers, vireos, flycatchers, and Scarlet Tanagers; most have gone, many have made it to Costa Rica.

A fair number are here on winter territory, searching for insects in tropical trees and avoiding the eyes of Bat Falcons and creeping Vine Snakes. Others are just stopping off to fuel up and continue to the incredible forests of the Amazon, or to find a sweet wintering spot in mossy rainforest of the Andes.

Rainforests at Bosque del Rio Tigre-excellent wintering habitat.

In a few months, a number of birders will also make a temporary migration to Costa Rica. They will visit to delve into tropical birding, watch toucan antics while delighting in the coffee fruits of volcanic soils, and photograph Purple-throated Mountain-gems (like the multicolored bird featured above). The birds are awaiting, I can promise you that! Here’s some other news items from October, 2022, Costa Rica.

Very Heavy Rains=Tragic Flooding and Road Closures

October in Costa Rica is bird migration but it can also be a month of rains. The rains from this past October have gone from being exceptional to extreme. Sadly, in the Central Pacific region, more rain fell in a day or two than typically falls over the course of the entire month. We’re talking about a country where it normally rains every afternoon of every day in October, we’re talking about a horrible deluge.

During the past week, so much rain came slamming down in the central and southern Pacific regions, parts of the town of Jaco flooded. Flooding also occured near Parrita and in some other areas, and landslides affected several roads. Although people weren’t swept away like the terrible climate crisis induced floods in Nigeria, Pakistan, and other places, in Costa Rica, a number of people have lost everything, businesses have been terribly affected, and many roads have been damaged.

Those roads will likely be fixed well before the high season but if visiting Costa Rica over the news few weeks, you will need to pay close attention to information about road closures. Keep an eye on whatever driving app you may use, especially if traveling anywhere on Cerro de la Muerte, Route 32, and other mountain roads, and anywhere from Tarcoles south to Panama.

Arctic Terns near Shore, Fewer Migrants?

Arctic Tern from a few years back.

On the bird migration scene, one of the more interesting sightings has been that of Arctic Terns on the central Pacific Coast. At least a few (and maybe more) were documented by local birders in the Playa Hermosa area, foraging close to shore. Typically, in Cosa Rica, this species is a bird of pelagic waters although perhaps they occur closer to shore more often than expected? Were they overlooked in the less birded past? Who knows but in any case, this us always an uncommon species for Costa Rica.

As far as other migrants go, some local birders have wondered if we are seeing fewer numbers. Although various factors cloud accurate assessment of abundance during migration, given the effects of climate disruption, insect decline, and other nasty factors on breeding grounds and migration routes, yeah, I bet we are seeing fewer birds. That would match the latest State of the Birds Assessment that shows continued declines in many species.

Off hand, I have had a strong impression of far fewer Cliff Swallows than other years and can’t help but wonder if this is related to so much of their western breeding areas being impacted by climate-change induced drought and heat waves. I have seen quite a few vireos and pewees but perhaps less than in previous years, and although there have been many Swainson’s Thrushes, there still doesn’t seem to be as many as in other years.

Hopefully, there will be good numbers of wintering birds; we do have a good amount of habitat for them.

Southern Nicoya Peninsula= Probable Migrant Hotspot

Once again, the southern Nicoya yields a rare for Costa Rica migrant. On October Global Big Day, Wilfreddo Villalobos found a small group of Bobolinks! The smart looking hay meadow birds might be regular up north but in Costa Rica, you would be lucky to add it to your country list. In common with other migrant hotspots, the southern Nicoya Peninsula is bordered on each side by water and thus could possibly act act as a “funnel” for migrants, or at least attract lost birds flying over the Pacific Ocean.

Any migrant effect isn’t as pronounced as that of the famed hotspots but the place certainly does attract rare migrants every year. I wonder what else is hiding in the tropical forests of that fun, underbirded area? What would a birder see while seawatching from the coast near Cabuya? Go and see what you find!

Rufous-vented Ground Cuckoo and Other Rare Resident Birds

The ground-cuckoo has been seen again at antswarms at the Pocosol Station. Honestly, this is no surprise, nor would it be surprising to find them at swarms in other suitable areas but given how generally difficult it is to see this species, it’s always good to know where and when they are being seen.

Another rare resident species seeen recently was a Black-and-White Hawk-Eagle at Nectar and Pollen (!). Lucky local birders had excellent looks at one that took to the air right in front of them! This site and other nearby sites are good places to look for this species but you still need a lot of luck to see one.
