Bridget brings up a very good question. I looked at several photos of the pelican seen at Hen Island on July 21 & 22. They show black on the head and the tip end of the lower mandible. According to info found in The Sibley Guide to Birds, that particular look fits well for an adult summer bird (Jun-Aug). Then on Aug. 10th myself & others got a very long distance look at a pelican at Campbell Bay and noticed that it was showing no black on the head, which at that time I mentioned in my eBird report that it "suggested" that this pelican was not the same pelican as the one seen 20 days earlier at Hen Island. I did a bit more research recently using The Sibley Guide again and saw that an adult non breeding bird (Sep-Feb) shows no black on the head or at the tip end of the lower mandible. Thus, the transition from adult summer plumage to adult non breeding plumage "appears" to occur during the months of July & August. On Aug. 24th, Henry Trombley & I saw the pelican at Campbell Bay from a canoe and saw that it had very little black showing on the head and no black seen on the tip end of the lower mandible. Now, because 20 days (pretty much 3 weeks) had passed between the two sightings (July 21-Aug 10), it seems "possible" to me that the bird seen at Hen Island "could" have had enough time to loose most of its' black markings. I am certainly no expert at determining that info so I cannot say for sure if that is true. However, it does seem (again-"possible") that the pelican seen at both locations "could" be the same bird.
It would be interesting to read others opinions on this.
