For 18 days we're adding a new Birdorable bird every day as part of our Birdorable Bonanza 2010. Today's bird is the Mourning Dove! Mourning Doves are widespread across North America, one of the most abundant birds on the continent. They are ground feeders, feasting on seeds and storing extra food in their crop for later digestion. Mourning Doves are common backyard feeder birds who will often spend hours pecking at seeds while remaining relatively still. Believe it or not, Mourning Doves consume up to 20% of their body weight every day. So that's how they maintain their pleasantly plump profile!

For 18 days we're adding a new Birdorable bird every day as part of our Birdorable Bonanza 2010. Today's bird is the Palm Cockatoo! Palm Cockatoos are very distinctive-looking parrots. They are slate-grey in color, with a featherless, bright red cheek. Their bills are extremely large, and they sport a long, scraggly grey head crest. Because of their rare beauty, Palm Cockatoos are very popular in aviculture. Despite their relatively small native range in Australia, the wild population is stable and not considered threatened.

For 18 days we're adding a new Birdorable bird every day as part of our Birdorable Bonanza 2010. Today's bird is the Brown-headed Cowbird! Brown-headed Cowbirds are well-known (and well-disliked!) for being brood parasites. This means they do not make their own nests. Instead, females lay their eggs in the nests of other birds. With this strategy, young Brown-headed Cowbirds are raised by the host parents, which can be as small as Yellow Warblers; more than 140 different species of birds have been seen raising baby Brown-headed Cowbirds. And cowbird adults don't have to deal with defending territories, building nests, or finding enough food to feed a brood of babies. The cowbird's "cunning," however, is the reason it is widely reviled. Because of some methods scientists believe cowbirds use to keep their host nest families in line, Brown-headed Cowbirds have been described as "Gangster Birds." Cowbirds can't really be blamed for their unusual species survival method, though. In fact, factors like prairie habitat loss, the wide extirpation of American Bison, and other human-influenced variables may contribute to Brown-headed Cowbirds turning to a wider variety of parasitic hosts.

For 18 days we're adding a new Birdorable bird every day as part of our Birdorable Bonanza 2010. Today's bird is the beautiful Gouldian Finch! The Gouldian Finch is one of the most wildly colored birds on Earth. Native to Australia, this little finch's plumage includes feathers of red, yellow, green and black. The head is either red, black or yellow. Formerly considered three different kinds of finches, we now know that these are actually color variants of the same species that exist in the wild. Yellow is the rarest. Because of their amazing plumage, Gouldian Finches are very popular in aviculture. Since 1959 it has been illegal to export the birds from their native Australia. Still, the species is considered threatened today, mainly due to habitat loss. Other factors contribute to the decline of the species, including easy predation - due to their bright colors. If you'd like to learn about the effort to conserve the Gouldian Finch in Australia, visit Save the Gouldian Fund.

For 18 days we're adding a new Birdorable bird every day as part of our Birdorable Bonanza 2010. Today's bird is the Western Scrub-Jay! Western Scrub-Jays are members of the corvid family, along with crows and other jays. You can find these blue beauties in western North America, ranging from southern Washington to central Texas and central Mexico. They prefer low scrub and oak woods. These extremely clever birds store surplus food for future use. They are also known to steal food from other birds. They will even take measures to protect their own food stores from other thieving birds! You could say they have some food issues. ;)

For 18 days we're adding a new Birdorable bird every day as part of our Birdorable Bonanza 2010. Today's bird is the Laughing Kookaburra! The Laughing Kookaburra is the largest species of the kingfisher family. These brown and white birds are named for their unusual call, which sounds like they are laughing: "koo-koo-koo-ka-ka-ka!" Although the species is native to eastern Australia, the unique call of the Laughing Kookaburra is often used by Hollywood as a sound effect in jungle scenes - no matter which continent. Have a listen to the call and see if you recognize it!

Laughing Kookaburras are fairly common within their range, often found in suburban or urban settings. They will even become habituated to humans. Last month one Laughing Kookaburra got into trouble after eating too many handout sausages. The bird became so overweight that it was unable to fly! Fortunately the bird was rescued and brought in to "bootcamp where it was expected to recover after being put on a diet and exercise plan.

For 18 days we're adding a new Birdorable bird every day as part of our Birdorable Bonanza 2010. Our third bird is the Prothonotary Warbler, a brilliant yellow in the forest. Prothonotary Warblers are among the most brightly-colored warblers. Males are brilliant yellow overall with blue-grey wings. Females are similar, but duller; both sexes have black beaks and bright black eyes. Prothonotary Warblers are named for their yellow coloring. Prothonotaries were clerks in the Roman Catholic Church who traditionally wore robes of deep, bright yellow.
