A team of researchers has found that the timing of spring bird migration across North America is shifting as a result of climate change. The study, one of the first to examine the subject at a continental scale, is published in Nature Climate Change. The work was done by scientists at Colorado State University, the Cornell Lab of Ornithology, and the University of Massachusetts.
Using 24 years of weather radar data, the study found that spring migrants were likely to pass certain stops earlier now than they would have 20 years ago. Temperature and migration timing were closely aligned, with the greatest changes in migration timing occurring in regions warming most rapidly. During fall, shifts in migration timing were less apparent. » Continue Reading.

A study published in the journal Science reveals that since 1970, bird populations in the United States and Canada have declined by 29 percent, or almost 3 billion birds, signaling what has been considered a widespread ecological crisis.
During the late 19th and early 20th centuries, the use of feathers in women’s hats was all the rage.
Cross-referencing a decade of Google searches and citizen science observations, researchers say they have identified which of 621 North American bird species are currently the most popular and which characteristics of species drive human interest. 
In the first global test of the idea, scientists have found evidence that some woodpeckers can evolve to look like another species of woodpecker in the same neighborhood. The researchers say that this “plumage mimicry” isn’t a fluke – it happens among pairs of distantly related woodpeckers all over the world. 
Using data on 77 North American migratory bird species from the eBird citizen-science program, scientists at the Cornell Lab of Ornithology say that, in as little as four decades, it may be very difficult to predict how climate change will affect migratory bird populations and the ecosystems they inhabit.
Under future climate scenarios, changing winds may make it harder for North American birds to migrate southward in the autumn, but make it easier for them to come back north in the spring according to researchers from the Cornell Lab of Ornithology.
Most songbirds migrate in darkness, usually when weather conditions are favorable. Tailwinds can produce massive migratory movements. Rain can shut down flights entirely.

The Cornell Lab of Ornithology and Alaska Organic Fertilizer company are offering grants to support school gardens in the United States, excluding it’s territories.
The third annual Global Big Day takes place on May 13, 2017. The term traditionally applies to any effort to identify as many bird species as possible in a single day. Bird watchers around the world are invited to watch and count birds for any length of time on that day and enter their observations online at
