2021 is over, yo! So it's time for the Annual Review Episode! 

We’ll be looking back at some highlights of bird science in the year 2021. What fascinating things did ornithologists and other biologists discover about birds this year?

I’ve picked 5 studies to highlight for you. These are stories that, in most cases, were interesting enough to make the news.
