Musings of a roaming nature nerd

River of Birds

During a cold, sunny October two years ago, Jason and I witnessed migration as never before. Atop a rickety wooden tower, on a pine ridge, in the middle of an isthmus, at Poland’s boundary with the Baltic Sea and Russia, we spent days mesmerized by a river of birds flooding over our head. Hundreds of thousands passerines and thousands of raptors winged their way toward the Mediterranean and Africa. Completely awed, we wondered if we would ever see such an event again.

Yesterday, here in California we once again observed a river of birds in motion. Black-vented Shearwaters are a species of seabird that nests on islands south of southern California, off of Baja Mexico. Only occasionally seen from land, these pelagic birds are most often found miles out at sea. And though their migration does not follow the traditional north-south-north pattern we think of for many birds, they are indeed moving in search of food, which is the reason why many birds migrate at all.

This year an El Nino event is developing in the Pacific and one possible result of that is a massive push of anchovies toward the coasts. In the wake of the anchovies are hungry birds, dolphins and numerous other sea creatures. Observing the movement and frenzied feeding of 20,000+ Black-vented Shearwaters was incredible. And not only were the Shearwaters in motion close to shore, but dozens of other species. Elegant Terns streamed overhead, every single one with beak-fulls of anchovies. Marbled Godwits and Long-billed Curlews foraged in the surf. The early morning sea air hummed with the energy of thousands of wings, churning waves, and the feverish excitement of a few SoCal birders!
