さえずり

Sweet, high-pitched 'tsee-tsee-tsee' whistle and soft melodic warbling. Flocks produce a continuous tinkling chorus. Alarm is a sharper 'tset'. Song is gentle and rhythmic.

About These Birds

シロエリハゲワシ

The griffon vulture is one of Europe's largest flying birds and a crucial scavenger in Mediterranean ecosystems. These social birds nest in large cliff colonies and can soar for hours using thermals without flapping. Vulture populations faced a crisis from the veterinary drug diclofenac, which proved fatal when consumed through contaminated carcasses.

Japanese White-eye

The Japanese white-eye is a familiar garden bird across East Asia, beloved in Japan where it is called mejiro. These sociable birds form flocks outside the breeding season and are important pollinators of plum and cherry blossoms. Unfortunately, introduced populations in Hawaii have become invasive, competing with native honeycreepers.
