Not all Snowy Owls migrate south, but the ones that do leave the Arctic tundra to winter over in North America arrive at their wintering grounds (areas such as the Massachusetts coastline) usually beginning in mid-to late-November. Some don’t arrive until December and some as late as January. They migrate along coastlines, prairies, river valleys, and even mountain ridgelines are thought to help guide the Snowies.
By mid-April, most Snowies have left Massachusetts, although one study that I read recorded a Snowy that did not leave Logan Airport until July 7th! Another study reported that in most cases, the Snowy Owls that did not leave until summer were non-breeding birds in their first year of life.
How long will Hedwig stay? She appears to be getting plenty to eat and is quite well adapted to backshore living, despite her throngs of weekend fans. Let’s hope her stay is a good one and that she returns to the Arctic this summer to make lots of little Hedwigs and Bubos!
- Watch from a comfortable distance–comfortable for the bird that is. Nothing makes the Owls more stressed than people getting too close.
- Please keep children from throwing rocks towards the Snowy or anywhere within the vicinity of the Owl.
- Please don’t allow dogs to play near the Snowies.
- There have been reports of Snowies flying into cars. They often fly low when flushed and it is easy to understand why this may happen, especially as the Snowies are drawing so much traffic. Please be on the look out when you are in known Snowy Owl territory.
- Slamming doors, radios blasting, barking dogs, and loud mufflers all stress the Snowies.
