I'm not sure I want to click on the, "pis". Wouldn't that be rather nasty and messy?
Those might be some sort of geese. They were honking like geese as they flew. I'm not sure if Swans honk but they look like Swans. Even though I am the "Bird Man", waterfowl and shorebirds are my two biggest WEAKNESSES in birding. EVERY birder specializes in certain groups of birds after awhile and are very poor or totally uninterested in identifying others. I specialize in Woodpeckers, Warblers,
bluebirds, and Vireos. I am weak in Sparrow and Hawk ID, and am ABYSSIMAL when it comes to shorebirds and waterfowl. On all other groups of birds I am about average. Warblers and Vireos are the two groups of birds that almost ALL birders specialize in.
