The rookery in the tops of the trees at the Lee Metcalf Wildlife Refuge is a busy place. Blue herons pick the tops of trees for their nests to avoid all sorts of predators. It's a strange site to see those large birds high in the evergreens.

The visitors center at the refuge has spotting scopes available for those who'd like to zoom in and see the nest-building that's finishing up. You'll note the sticks in the beaks of the heron in the photos.

When the young birds join the the crowd, it will get even busier. We'll keep you informed.

In the meantime, we'll be sharing some great photos of the activities.
