Nests!

Let's talk nests!  Every animal has a home--some are below ground in burrows and dens and some are above ground in huts and tree cavities!  Many, however, are high up on the branches of trees among the leaves!  Both birds and many squirrels build nests in trees to keep hidden from and out of reach of predators.  When squirrels cannot find a tree cavity to nest in, they will build their nests in the crook of a tree's trunk and a branch using small twigs loosely woven into a mat and then covered with lots and lots of leaves!  Birds, on the other hand, build their nests on tree branches using many different building materials including moss, sticks, feathers, dried grasses, and mud, just to name a few!  Below are pictures of nests--can you figure out which nest belongs to a squirrel and which belongs to a bird?

You will see many nests when you hike River Bend's trails!  Here's a challenge for you on your next visit: how many bird and squirrel nests can you find on your hike!  Then, return a couple of weeks later--can you still find as many nests?  Before the leaves begin to unfurl, you may see an increase in the number of bird and squirrel nests!  As birds migrate back to Wisconsin from their over-wintering grounds in the south, they will need to build nests to live in!  Additionally, as young squirrels leave their birth nests, they will also need to build nests for themselves to keep hidden and out of the elements.  Once the leaves come out, however, it will be harder to find these nests because the leaves will hide them, keeping them safe!

Many animals are hungry this time of year--especially birds returning from their spring migration and squirrels who have run out of their food caches (where they've hidden their food).  Do you want to help the birds and squirrels at your house?  Make some feeders!  Check out the links below for great ideas on bird and squirrel feeders to hang outside.  Remember to keep your feeders safe--place them well away from your windows to avoid bird strikes and away from large trees to avoid predators like cats!

Critter Corner!

Last Week's Answer: North American Raccoon! (AKA: Procyon lotor)
FACT: There are seven species of raccoon all over the world and Christopher Columbus was one of the first to write about them!  Many people believed that raccoons were related to dogs, cats, badgers, and even bears!  Then, Carl Linnaeus, the 'father of modern taxonomy', named it Ursus lotor, which means 'washer bear' because he believed raccoons were related to bears (Ursus) and because raccoons like to 'wash' (lotor) their food in water before they eat!  Later, scientists decided raccoons were not related to bears and placed them in their own genus Procyon, which means 'before the dog' or 'doglike'.

Can you name this week's mystery animal below?  Hint: River Bend's Root River is home to a large rookery of nests where parents raise their chicks together until they fledge and leave the nests! The answer will be posted in next week's edition!

That's all for this week--thanks for reading!
Stay wild and free and healthy as can be!
