Northern Cardinal
Woodland edges, thickets, gardens, and suburban areas. Prefers dense shrubby habitats for nesting.
Song & Call Comparison

Northern Cardinal
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
African Penguin
The African penguin is the only penguin species native to the African continent, also called the jackass penguin for its donkey-like braying call. Their population has plummeted over 95% since pre-industrial times due to egg collection, oil spills, and competition with commercial fisheries for sardine and anchovy stocks.
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.
