I’m reading a marvelous book on migration called ‘Living on the Wind‘ by Scott Weidensaul. Local birders recommended it to me as the No. 1 book on their list of books about ‘migration’. A must read if you are looking for a good book on migration and love birds like I do.
Photos below: Male and Female Dark-eyed Juncos. Juncos are residents of the Central Coast but the numbers increase during migration. Sparrows travel 3,000-4,000 miles non-stop until they arrive at their destination for winter. Migration is a fascinating phenomenon. Birds migrate for food and not due to cold weather. Biologists have discovered that the internal organs of some species will atrophy allowing them to store more fat for their long journey.
