Red-masked Parakeet Aratinga erythrogenys and Grey-cheeked Parakeet Brotogeris pyrrhopterus: two threatened parrots from Tumbesian Ecuador and Peru?

Biodiversity and Conservation in Tumbesian Ecuador and Peru

expertise, and which conservationists are doing what ± all in splendid detail. The main aim is to help conservation planners to zero in on those areas that should be protected as a matter of top-line priority. That is to say, the books describe a large number of localities where exceptional amounts of biodiversity face exceptional threat of habitat destruction: hot spots writ large. If only we ...

A parakeet genome project?

Researcher William Haseltine, head of Human Genome Sciences Inc. in Rockville, Maryland, likes to claim that knowledge from the human genome, combined with a few technology breakthroughs, will someday enable humans to live forever. Most researchers who study aging have more modest expectations--for example, trolling the genome for new insights into genes involved in so-called oxidative damage t...

Feeding ecology of the Green-cheeked parakeet (Pyrrhura molinae) in dry forests in western Brazil.

The genus Pyrrhura includes small to medium-sized parakeets, which inhabit both low and dry alongside tall rainforests, mainly in South America. Pyrrhura molinae is still common, year round, in the markedly seasonal forests of western Brazil. This parakeet, as well as most Neotropical parrots, continues to be poorly understood. Hence, in the present study I examined their foraging ecology both ...

Parakeet Damage to Sunflower in Pakistan

Rose-ringed parakeet (Psittacula krameri (Scopoli) damage to sunflower heads was estimated in two provinces of Pakistan during the spring of 1981. In seven districts of Punjab the damage ranged from 5.0-23.28 %, with an average of 11.72 %. In rainfed areas the damge was as high as 71.43%, with average of 38.29%. In Sind the damage was on the higher order. In nine districts the damage ranged fro...
