How do the birds know when it's time to fly back north?
This week has brought many old faces back to my yard -- Robins, Sandhill Cranes, Red-Winged Blackbirds, Kildeer, Canadian Geese, Finches, and more.
I step outside my front door and it is no longer silent -- there is a symphony of song.
My birdfeeder is the local hangout spot. I now have to fill it about every three days.
There is even a Hooded Merganser duck swimming around in the pond behind my house. His stay here will be short as he heads even farther north.
The funny thing is that I never really see the birds migrating -- they just show up.
How do they know?
