How an Owl Hears: Five Key Facts

Owl Hearing Explained
Nature never does anything without a reason and there’s a reason for everything that birds do, such as why hawks and eagles hunt during the day and most owls hunt at night. In ecology lingo it’s called “habitat partitioning,” which means using different parts of the habitat at different times or in different ways and not overlapping. This allows predatory birds like eagles and hawks to avoid conflict, and mice to be terrified 24 hours a day (it’s rough being lowest on the food chain).
Hunting at night isn’t nearly as simple as hunting during the day. Night hunters can’t use their eyesight very well (except during times of the full moon), prey animals can hear them coming (because it’s more still), and they have to land on a scampering wee beastie that is moving lightning fast (in, under, and around things) on the forest floor (or flying) with accuracy. Not much to ask eh? Owls are spectacular hunters, and I’ve come to appreciate their adaptations for catching prey, in particular their accuracy and hearing. That's why I thought I'd do a post on how an owl hears.
What's the Best Bald Eagle Cam?

Bald Eagle Cam Suggestions
Living in the nation's capitol comes with a certain panache of patriotism, and with that DC has gone bald eagle crazy for the latest round of chicks that have hatched at the National Arboretum. You can watch every move of mom and dad eagle, every pip of the eggs hatching, and the woozy wobbling of the young in real time on their eagle cam (short for camera). It's fascinating, and unpredictable. I would also venture it's something like watching fish in a tank, it is relaxing and lowers blood pressure too. In light of this I thought it would be useful to list some of the best live eagle cams on the web.
Short-eared Owls and Their Winter Visitation

Introduction to the Short-eared Owl and What To Look For
Most people are pretty familiar with at least some of the owls of North America, including barn owls (big, white pretty owl), barred owls (the ones that say "who cooks for you" when they hoot), great horned owls (the really big ones that make characteristics hooting), screech owls (cute little fuzzy things that sound terrifying, like whinnying horses), and of course snowy owls (made famous by Harry Potter). However, there's an owl that is just as common that few people know about, and it is currently coming down from Canada and the Arctic, visiting all of North America. It is the short-eared owl. In this post I'll tell you what to look for and where, so you can start to keep an eye out for amazingly beautiful owls, because they're actually easier to see than most other owls.
A List of Hawk ID Guides and Resources

Hawk ID for Hawk Watching
Just out of college I began hawk watching for fun, and worked with Hawk Watch International through the forest service. I moved on to hawk watching at the Grand Canyon for a season, then later to the shores of Delaware and now Maryland. I like to encourage all beginning birders to start with raptors because they are charismatic and fairly easy to learn. No matter where you go in the US, raptors are there and they are magnificent birds to watch and enjoy. When I first started learning about raptors I was given a set of books that have stayed with me on all my journeys. Now, there are even more resources than when I started, including free online guides. However, I also like to encourage beginning and intermediate hawk watchers to stay low-tech and use paper based-field guides. I've already written a post about how to choose the best bird field guide, but I want to provide you with a list of hawk ID guides that you can use to prepare for hawk migration or for IDing hawks you're already seeing.
