It appears that the swan migration is now in full flight, with swans (both Trumpeter & Tundra) flying regularly through Calgary, Alberta, CA.
Only time will tell how many will actually overwinter here, having discovered that there is plenty of open water and food available on the Bow River for the duration of the Winter. Believe those that stay have worked out that they can go half the distance, spend half the calories in flight exertion and have a head start come Spring. Perhaps even have their choices of the best nesting areas having arrived a little earlier than those coming up from further south.
And in this fall migration, it was lovely to see so many families, with adults having more than one youngster accompanying them.
