Alternate names: White-collared Seedeater, Sharpe's Seedeater
- Sporophila morelleti
Identification
Length: 9½–11¼ cm (3¾-4½ inches).
This is a small finch with a short, stubby dark bill and curved culmen and short tail. The breeding male has a dark head and back, a variable white collar and black breast band, variably buff belly, double white wing bars and white rump. The winter male keeps the blackish wings, whitish wing bars and white spot at the base of the primaries. Its crown is still mottled with dark, but is otherwise similar to female.
Females are much less patterned, and are buffy brown above with two white wing bars.
Variation
The black bib/breast band and the white collar in the male varies between weak in subspecies sharpei and much stronger in e.g., moreletti[2]. The second has underparts white to pale buff.
Similar Species
Cinnamon-rumped Seedeater of West Mexico is similar but lacks wing-bars. Within its range, the male Ruddy-breasted Seedeater in breeding plumage has a two-toned plumage, gray above and ruddy below. Female and winter male Ruddy-breasted are more similar to female Morelet's, but Ruddy-breasted is smaller, with a paler bill and more contrasting wing edgings. It also lacks wing bars. The male Variable Seedeater is almost all black. Female Variable Seedeater does not have wing bars, and is more olive in color.
Distribution
North America and Central America. Eastern Mexico and the far southern Rio Grande Valley in Texas; additionally along the Caribbean slope south to western Panama.
Taxonomy
The former White-collared Seedeater has been split into this species and the Cinnamon-rumped Seedeater.
Subspecies
This is a polytypic species consisting of two subspecies[1]:
- S. m. sharpei:Black breast band of the male is reduced to black mottling at the sides of the breast. Back grayish brown, mottled with black.
- S. m. morelleti:Black breast band of male is complete; black on back is more extensive; and has white crescent below eye.
Proposed subspecies S. m. mutanda in which some males have a black throat is considered a synonym of nominate.
Habitat
Open grassy areas, pastures, roadsides, weedy fields, moist savanna, and marshlands with tall reeds.
Behaviour
Diet
Eats mainly grass seeds, augmented with a few berries and insects. Will jump into air to catch flying insects.
Breeding
Begins in late March and continues into summer in Southern Texas; begins in April in Northern Central America. Nest built by female, taking 5–6 days. Three to four eggs are pale blue to greenish blue with speckles, blotches, or spots of deep brown or black.
Vocalisations
Song high-pitched and canary-like, a clear sweet sweet sweet cheer cheer cheer followed by various trills.
