Snowy Owls May Provide Early Indications of Climate Change

Snowy OwlOwls are great favorites of mine, and I’ve had the good fortune to work with and observe many species in both captivity and the wild (please see articles below).  One of my most memorable wild owl experiences occurred, surprisingly, in the Bronx, when I was but 6 years old.  A huge Snowy Owl perched on the roof of my home for 4 hours, awing me as had nothing else.  I quickly learned that Snowy Owls travel south from their Arctic haunts when their primary prey (a small rodent known as the Lemming) is in short supply.  Now biologists are finding that the close ties between Lemmings and Snowy Owls may provide important information concerning climate change.

Breeding Canaries, Waxbills and Other Finches – The Importance of Insects

Red-billed FirefinchWild finches of almost every species consume beetles, spiders, caterpillars and other invertebrates throughout the year, and in large quantities both before and during the breeding season.  While those we keep as pets may thrive on seed-based diets, providing them with a variety of insects will improve their health and encourage breeding.  A reader’s note concerning his success with Bronze-Winged Mannikins and the onset of the spring breeding season here in the Northern Hemisphere have sparked me to take another look at this important topic.

New Evidence Proves that the Ivory-Billed Woodpecker is not Extinct

Ivory billed WoodpeckerOne of the USA’s most hotly-debated conservation questions seems finally to have been answered.  For years, ornithologists have considered the huge Ivory-Billed Woodpecker, Campephilus principalis, to be extinct, but many well-respected biologists continued to report sightings.  Down to an estimated 30 birds by the 1930’s, none had been observed for decades despite intensive searches and rewards, including one of $50,000 posted by the Cornell Lab of Ornithology.  Recent video and acoustic recordings (Journal of the Acoustical Society of America, please see below), however, seem to establish that this magnificent bird is still with us.
