From “Ornitologia Brasileira” by Helmut Sink

Being an early bird isn’t all it’s cracked up to be. 🥚 Using our egg collection, Curator of Birds John Bates determined many of Chicago’s birds are laying eggs about a month earlier than they did a century ago. ⏰ 📸: Bill Strausberger

While birds laying their eggs a few weeks early may seem small, John Bates notes that it’s part of a larger, developing story about how animals are responding to climate change and competing for resources in ways they didn’t need to in the past. 🐦 📸: John Bates

Biologists : Anyone know of a particularly good talker on the topic of.... mules?? And biology of hybrids in general and also, fertile mules (they are a thing sometimes!). Looking for someone super passionate and knowledgeable about nature's hybrids!

So fortunate to spend the past month in Brazil gathering research & referencing the collections of Museu de Zoologia da USP. Muito obrigada Museu de Zoologia
