This bird has probably just finished a winter migration from perhaps Alaska or Yukon to Argentina and back up again, a trip possibly of 20,000 kms! Swainson's Hawks are noted for the longest migrations of any raptor in North and South America.
I have spotted them in Aurora, Ontario for the past two years and except to see them again this year.
More to come shortly, I hope...
Please comment if you wish.
