The subject has probably been beaten to death at this time!
However, I've been traveling for the past month and have just returned to hear about these guys and their visit to the BB dykes.
Does anyone know:
1. If they are still there?
2. How long they have been there?
3. How long they are likely to remain?
Is it unusual for such a large flock to visit the lower mainland?
2. couple of months at least
3. who knows
A group of owls is called a parliament. It is unusual to see a large number of owls together. According to the April 2012 of BirdWatching magazine B. Bay has the largest number of owls. Ocean Shores WA had up to 13 owls, Polson Montana had 14 or 15 owls, South Dakota had at least 20 owls in Dec. It also says ebird collected 4,250 reports of snowies.
