In Maine now we have robins spreading out. My son saw a flock of 50 mallards heading north, and a neighbor saw a flock of 100 Canada geese flying north as well. This has all been within the last 3 weeks. -All ahead of schedule by a month or so. Thursday I saw a red tail hawk taking off from a tree by the side of a rural road.
As a kid I started recording arrival dates for Redwing black birds. It is really an accurate occurrence. If the winter is mild- you move the arrival date up a week, and if cold, postpone it a week. Then you watch to see what you get. Redwings are so noisy that they are good indicators to watch for.
But as someone said- peepers at night, and during the day- song sparrows!
I know spring is on the way- I had a dream of a meadowlark!
