That Bird Blog – Bird Care and History for Pet Birds

Toys are more than just “time fillers” for parrots.  Social and highly intelligent, pet parrots suffer badly when bored, and soon exhibit destructive behaviors or stress-related illnesses.  Zoos are now requiring that toys and foraging opportunities (they call it “Behavioral Enrichment”, sounds better in journals!) be provided to animals ranging from frogs to elephants.  A study recently published in Applied Animal Behavior Science (V.120, N.3) has revealed that, at least for Orange-Winged Amazon Parrots (Amazona amazonica, please see photo), all toys are not created equal.

Parrot Preferences: What and Why

The study compared the reactions of parrots to wooden toys differing in size, color and harness and to rawhide toys that varied in color.  The toys were attached to computer-monitored switches, so that the birds’ reactions would not be influenced by observers, and could be recorded round-the-clock.

Recent studies of the Gouldian Finch (Erythrura gouldiae), an endangered species and popular pet, have revealed that females readily copulate with males other than their mates in order to ensure that the young acquire the best possible genes.

Risky Behavior

Working with finches in captivity and in their natural habitat (Northeastern Australia), researchers at Australia’s Macquarie University found that paired females will indiscriminately cheat on their mates when given the opportunity.  This behavior puzzled he researchers since, if discovered, the females risked abandonment by their mates and would likely be unable to raise their chicks alone.

People have long pondered the role that “looks” and personality play in our personal relationships.  Recent studies of the House Finch (Carpodacus mexicanus) suggest that similar considerations may arise when birds go courting as well.

Drab Plumage…No Problem!

Working with wild House Finches in Arizona, ornithologists from Cornell University and the University of Arizona determined that females preferred brightly-colored (red) males to duller, orange/yellow individuals (American Naturalist, September, 2010).  The somberly-colored males, however, were not so easily put off.  It seems that, in order to compete with “handsome” males, they become more sociable – “friendlier”, if you will – and in that way attract the attention of the otherwise uninterested females.  Read More »

We’ve known for some time now that the eyes of Budgerigars and African Gray Parrots are UV-sensitive and can detect UV light.  Humans cannot, but like parrots we are active by day and exposed to UV light throughout our lives.  In many cases, parrot and human life-spans are similar in length, yet, in contrast ourselves, our avian friends’ eyes do not suffer UV damage.  A study at the University of West Australia is seeking to find out why.

Passionate birders are a breed apart – I know folks who think nothing of flying from NYC to Argentina at a moment’s notice in the hope of spotting a non-descript sandpiper that happened to show up unexpectedly.  Some such people, however, sometimes (rarely!) manage to talk non-birders into becoming their significant others, in which case such excesses might be frowned upon.  Then there are those who enjoy bird-watching, but would like to also swim, ski or visit museums on their vacations.  Fortunately, there are options that can accommodate all levels of bird-watching enthusiasm.

Birding Plus…

The Sierra Club, the USA’s oldest grassroots conservation organization, sponsors a number of Volunteer Vacations – trips that include birding and conservation-oriented activities while leaving time for other pursuits as well. Read More »
