White-fronted Nunbird Costa Rica

2021 is already well underway, are you birding? I hope so because watching a flock of redpolls bound through wintery airs that echo with the calls of crows is nature connection magic. Tracking the soaring of a Bateleur in hot African skies is a lifetime gift. Watching Baltimore Orioles consort with Blue-gray Tanagers as Great Kiskadees throw down their wings and yell is the perfect start to any day.

I saw some of that avian action this morning.

During anxious times, birding is therapeutic, it brings us back to center, can wipe away the worries and act as a source of mental fortitude. Watch some birds today and see where it takes you. Watch some birds all year long and enjoy the journey, keep a list. I follow the year list birding tradition. I’m not sure when it started, who ever kept the first list, but it gives me something to strive for, facilitates noting each special moment like when I saw that first Painted Bunting of 2021.

I saw a male just out back this very morning. It flew to some bare branches near a Yellow-throated Euphonia and a pair of Blue Grosbeaks.

I can also note my first White-fronted Nunbird, I had a few at Tirimbina Reserve just the other day. 

Although I would love to see some birds elsewhere, even if I don’t, my year list will make for some fun documentation. After all, Costa Rica is no small player on the world birding stage. We have nearly 930 species on the official list and with some effort, 700 in a year is a feasible goal. Here I go, I hope you also surpass your birding goals in 2021.

Patrick O'Donnell became a birder at the age of 7 after seeing books about birds in the Niagara Falls, New York public library. Although watching thousands of gulls in the Niagara Gorge was sublime, more bird species (and warmer weather) eventually brought him to Mexico, Costa Rica, Ecuador, and other very birdy tropical places. A biologist by training, he has worked on bird-related projects in Colorado, Washington, Peru, and other locales, and has guided birders in Peru, Ecuador, and Costa Rica. These days, he lives in Costa Rica where he juggles guiding, freelance writing, developing bird apps for Costa Rica and Panama, posting on his Costa Rica birding blog, and discussing dinosaurs with his young daughter.
