Blackbirds Breeding Killing 
10,000 Birds

That unwanted yet predictable final bit of killing cold weather was and is why most of the colorful insectivores, the true birds of summer, remained far to the south until May. Wilson’s Plovers are in Breeding Plumage. More Birds are Singing. Spring in Costa Rica is more of a transfer from dry to wet than from cold to hot.

The juvenile Chinese Blackbirds get older but still look kind of stupid. But the stars of the month were some breeding Eurasian Tree Sparrows. Tragically, I never saw any birds near the nest later on – I guess they abandoned it, decided to quit procreating, or just got eaten by some other bird or cat.

I was fortunate to rack up a number of lifers in 2013, both at home and abroad ( Varied Thrush in Washington, Brewer’s Blackbirds in California, Burrowing Owl in the Nevada desert). Meredith enjoyed her first sighting of an awesome migration spectacle. She blogged about it here.

More than 99% of the population of Tricolored Blackbirds ( Agelaius tricolor ) live within the state of California and form the largest colonies of any North American passerine bird 1. The Results of the 2014 Tricolored Blackbird Statewide Survey confirm that this species is in rapid decline. Click on photos for full sized images.

In my homeland, some 800 km / 500 mi further north, these ducks are common on migration but very rare in the breeding season and I realized that these are my first young birds – ever. What is killing them? Yet, what is killing the birds of Lake Karla? Spring (migrants and breeding species) and winter (wintering waterbirds).

But something happened, and it happened many times: Something has been killing our Blackbirds. We interrupt this blog post for an important message: This is the kind of Blackbird I am talking about, the Eurasian thrush that is Turdus merula, and not the American group of iconic Icterids you might have had in mind.

High overhead, swallows are going over and in the fields, blackbirds move in undulating flocks. However, even now, the ancient movements of birds between summer breeding grounds and tropical wintering places have been taking place in Costa Rica. We see fall-plumaged wood-warblers busy in the maples.
