New wetlands? Good idea. Only, sometimes it's Ma Nature herselrf who creates them, as in Hunza, where a rockslide dammed the Hunza river less than ten years ago, creating a large lake and burying the highway that links Xinjiang Province with Pakistan.

I've also seen hundreds of beaver dams, whle on a canoe trip in central Maine.

I don't know if egrets are considered especially beautiful compared with other birds, but they are certainly graceful-looking. They are there to keep the local fish and mouse populations in line .

Hello! Yes cool how in nature things change all the time, providing new habitats and such. I think beavers are cool! Sad we don't have anything like that here in Africa.

Well I consider the egrets very beautiful! But so are pretty much all other birds ...

Every day I see dozens of birds. Mostly they are small and some combination of brown and gray. They're all so lively and alert, though! They're beautifully formed. Maybe a lot of them are sparrows and chickadees.

Blue jays and robins visit my yard rather a lot. The robins probably want tasty earthworms (I constantly work to improve the soil fertility here, which gives worms rich, organic material to process). Every time Ip lant something new, I find earthworms in the soil.

Blue jays eat acorns, nuts, seeds, grains, and berries. Plenty of those around my yard.
