It has only been the last few years that I have seen white pelicans in the Denver area. They arrive in late Spring and stay for awhile before heading North. I saw this flock a month or so ago. They are huge with incredible wing spans. I think they are terrific!
They reminded me of this poem, possibly by Ogden Nash or Dixon Lanier Merritt--there is some dispute.
A wonderful bird is a pelican,
His bill will hold more than his belican.
He can take in his beak
Food enough for a week;
But I'm damned if I see how the helican.
Have a great day!
