[Tweeters] Are our "early" Ospreys not "arriving", but only

7 of the 8 Ospreys I saw on March 20th of this year were perched on
sacrificial utility pole nests. The other was perched on a Cottonwood limb
-- a Cottonwood in which I often see an Osprey perched from spring through
summer. One of those nests now seems to be occupied by a Canada Goose. I
presumed they all intended to spend the season here.
