Eastern Bluebirds - why are they overwintering here?!

Bluebirds are determined little birds.  They were endangered in the 60s and 70s, but have made a huge comeback. Most Bluebirds do fly much farther south for the winter, but some stay here and have found ways to survive the extreme cold, and to adapt to changing food supplies.  They appear in large family groups, and often several family groups will flock together.)  We have seen as many as 12 Bluebirds ringing our heated birdbath at once (fresh water is a must if you want to attract them in the winter.)  Insects will always be the preferred food of Bluebirds, but berries and other foods such as peanuts, chopped suet, sumac fruits and mealworms can sustain them in winter. Read more about Bluebirds!»
