While driving north from New York City to New Hampshire, reader Liam Coyle spotted this large flock flying overhead, just after crossing into Connecticut on I-95. What are these birds?
Answer
These are great blue herons migrating to their breeding grounds. Herons’ migratory behavior is variable; some migrate solo, others in groups of 3 to 12 birds, and occasionally in larger groups. (To learn more about great blue heron migration, check out the Forest & Wildlife Monitoring column from the Winter issue of Northern Woodlands).
