Signs of spring

It's been an exciting couple o weeks here in Burlington. In addition to the dramatic sighting of a moose in our yard!!, we've had a number of other visitors. This morning a catbird was singing. Yesterday, a house wren. And persistent throughout has been the large flock of juncos and white-throated sparrows (some chipping sparrows mixed in as well). 

Female dark-eyed junco (females have more brown on sides than males and are less bicolor)

Chipping sparrow

The aptly named white-throated sparrow. Song is a whistle-y "Oh Sweet Canada Canada Canada"
