Burung kicau (Songbirds)
Sprague's Pipit
Anthus spragueii
- tidak umum
- 40 km/h
- Rentan
Sings while spiraling so high you can barely see it. Audio delivery from 300 feet up.
- Populasi
- Approximately 1,400,000 mature individuals globally, with a decreasing trend; data separately show roughly a 90% population loss since 1967
- Habitat
- Native short- and mixed-grass prairie of the northern Great Plains; requires large, unbroken tracts of undisturbed or lightly grazed grassland and largely avoids cropland, overgrazed pasture, or land with heavy shrub encroachment
- Fakta menarik
- Unlike most songbirds, the male Sprague's Pipit delivers its tinkling, high-pitched song not from a perch but from a sky-high circling flight that can reach roughly 300 feet above the prairie and sometimes last close to an hour, making the bird far easier to hear than to see.
- Sebaran
- Breeds across the north-central Great Plains of south-central Canada (Alberta, Saskatchewan, Manitoba) and the north-central United States (Montana, North Dakota, South Dakota, Minnesota); winters in the southern US (e.g. Texas, Arizona) and northern Mexico
- Makanan
- Mostly insects and other arthropods during the breeding season (grasshoppers, crickets, beetles, weevils, leafhoppers, ants, sawflies, moth and butterfly larvae, spiders); supplements with grass and forb seeds outside the breeding season
