It's nesting time, and many people get in touch with us every week with questions about what to do if there is a nest near their house, if eggs can survive being left uncovered, how old chicks are when they leave the nest, and more. If you've ever asked a question like this about bird nesting, check out our livestreamed Q&A session with NestWatch project leader Robyn Bailey:

QUIZ ANSWER. Hummingbirds are simply amazing, but they can be hard to identify especially when they zip past at great speeds. That's why it's important to note size and shape as well as feather color. Although size can be difficult to judge in a photo, this one does look particularly small and compact. Its tiny tail barely extends beyond its wings and its bill is short and thin. Rufous and...

Grasshopper Sparrows are widespread across North America, if sometimes hard to find. But a subspecies that lives in Florida's dry prairie ecosystem is highly endangered. This photoessay from our magazine explores the Florida Grasshopper Sparrow, its threats, and the biologists working to save it:

Our latest Bird of the Week brings a smile of delight as it returns to backyards at this time of year across central and eastern North America. Males have a bright red bib contrasting with their sophisticated looking black and white plumage. Females and young are a mix of streaky browns, and both sexes have large beaks that make quick work of sunflower seeds. Their song has been described as...

There's lots of great boreal forest in western Canada and Alaska, so why don't more warbler species breed there? A new study says it might have less to do with the habitat and more to do with the commute. Read more at All About Birds:

QUIZ ANSWER. The long tail and long, slender body are clues that point towards the cuckoo family. Not many other species in the U.S. have such a long and sleek body shape. They also tend to perch more upright, another good clue. Yellow-billed Cuckoos have a yellow bill and large white crescent-shaped spots that are visible under the tail. The quiz bird has a black bill and thin white tips...

The breakdown: 242 species from Belize, 224 from Mexico, and 213 from Guatemala. Full wrap-up coming to All About Birds tomorrow. Congratulations Sapsuckers and thanks to all who...

We're wishing a happy Mother's Day to all the mothers out there! The bird world has some great moms in it, too, like these fairywrens from Australia. They call to their chicks while they're still inside the egg, helping the young learn their calls before they've even hatched.

We're still waiting for word of the final tally for Team Sapsucker's Mexico, Belize, and Guatemala lists. But as of last night, more than 12,000 people had reported more than half the world's bird species for Global Big Day! Congratulations! Browse results here, and if you went birding yesterday be sure to enter your own checklists into @eBird so they can be counted!

Down in the Yucatán Peninsula, Global Big Day is winding down—at least the daylight portion of it is. Sunset finds the Guatemala team afloat on Lago Petén Itzá hoping for a few last waterbirds. They're on pace for setting a new Guatemala Big Day record. Wish them luck!

How's your Global Big Day going so far? Right now South America is edging out the rest of the continents with just over 1500 species reported, but the Eastern Hemisphere has the upper hand over the Western with more than 2500 species. But there's still plenty of daylight before the sun sets over Hawaii. What's your best bird of the day?
