A study published in the journal Science in 2019 found that bird populations in North America have taken a nosedive in the last 50 years. By crunching data from citizen scientist counts and surveys, scientists found that there are three billion fewer birds than there were in 1970.
One
species that has taken a heavy hit is the tricolored blackbird, whose
population has plummeted from several million in the mid-19th century to less
than 180,000 today, according to Audubon California. In response to the
population crash, a band of individuals and conservation organizations are
finding creative ways to bring this bird back from the brink.
