Eight bird species are first confirmed avian extinctions this decade
Most of the extinctions were caused by deforestation in South America, a new
study of endangered birds shows
Spix’s macaw, a brilliant blue species of Brazilian parrot that starred in the
children’s animation Rio, has become extinct this century, according to a new
assessment of endangered birds.
The macaw is one of eight species, including the poo-uli, the Pernambuco
pygmy-owl and the cryptic treehunter, that can be added to the growing list of
confirmed or highly likely extinctions, according to a new statistical analysis by
BirdLife International.
Historically, most bird extinctions have been small-island species vulnerable to
hunting or invasive species but five of these new extinctions have occurred in
South America and are attributed by scientists to deforestation.
Stuart Butchart, BirdLife International’s chief scientist, said the new study
highlighted that an extinction crisis was now unfolding on large continents,
driven by human habitat destruction.
“People think of extinctions and think of the dodo but our analysis shows that
extinctions are continuing and accelerating today,” he said. “Historically 90% of
bird extinctions have been small populations on remote islands. Our evidence
shows there is a growing wave of extinctions washing over the continent driven
by habitat loss from unsustainable agriculture, drainage and logging."

when you got birds like the brown headed cow bird that parasite nests and lay their own egg for the unsuspecting parent to raise it is no wonder why.
in South America it is the cuckoo bird that does the same. if those type of birds are not controlled there will be many more.
Texas has taken step to eliminate the Brown Headed Cow bird with traps and eliminated some 14,000 if I remember right.
there is a PBS video on youtube killer birds or gangster birds.
