Mountains, cliffs, and open grasslands. Nests on cliff ledges in colonies. Requires thermals for soaring flight.
Northern Cardinal
Woodland edges, thickets, gardens, and suburban areas. Prefers dense shrubby habitats for nesting.

Loud, clear whistled phrases: 'cheer-cheer-cheer' and 'birdy-birdy-birdy'. Both male and female sing; female song is softer. Alarm is a sharp metallic 'chink'.

About These Birds
兀鹫
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.
Northern Cardinal
The northern cardinal is the state bird of seven US states, more than any other species. Unlike many songbirds, both males and females sing, often in duets. Cardinals do not migrate and their brilliant red plumage against winter snow makes them a favorite among backyard birdwatchers.
