The following is a photographic rendition of what the purple sandipiper that flew past us and landed for less than a minute each on Tiscornia Beach, and the North and South Pier, might have looked like if it had rested on say, an algae covered rock, instead of a concrete pier, and sat for an hour, instead of running around constantly, in nice morning light, rather than heavy overcast. Tim managed a few IDable frames with the SLR, but my digiscoping efforts were futile. The pic is from New Buffalo about 3 years ago.
Next is a Ross's type goose that was in the rivermouth. It would appear to be the same bird as Tim found at LMC about a week ago.
Interestingly, Trauger concluded in 1971 that intermediate birds comprised about 5% of the Ross's population and felt that it was possible that "pure" Ross's may in the future cease to exist as the population becomes swamped with Lesser Snow Goose genes. As an example, he reported data suggesting that Black Ducks were outnumbered by Mallards by about 6:1 in North America, whereas Ross's goose was outnumbered by about 27:1 making hybrid pairings even more likely. I'm not sure that these Arctic geese aren't any different from the Arctic gulls; who knows where Kumlien's stops and Thayers begins in many individuals, the same may be becoming true for these.
