27-3-2017 RANCHO NATURALISTA - WHITE NECKED JACOBIN (FEMALE) (Florisuga mellivora)
The white-necked jacobin (Florisuga mellivora ) is a medium-size hummingbird that ranges from Mexico south through Central America and northern South America into Brazil, Peru and Bolivia. It is also found in Trinidad & Tobago.
Other common names are great jacobin and collared hummingbird.
The white-necked jacobin is 11 to 12 cm (4.3 to 4.7 in) long. Males weigh 7.4 to 9 g (0.26 to 0.32 oz) and females 6 to 9.2 g (0.21 to 0.32 oz). The male is unmistakable with its dark blue head and chest and white belly and tail; the tail feathers have black tips. A white band on the nape separates the blue head from the bright green back and long uppertail coverts. Females are highly variable, and may resemble adult or immature males. The majority of females have green upperparts, a blue-green throat and breast with white "scales", a white belly, and a mostly green tail with a blue end. Immature males vary from female-like, but with more white in the tail, to male-like with more black there. Immature females also vary but usually have less white in the tail and are somewhat bronzy on the throat and chest.
The white-necked jacobin inhabits the canopy and edges of humid forest and also semi-open landscapes such as tall secondary forest, gallery forest, and coffee and cacao plantations. It is usually seen high in trees but comes lower at edges and in clearings. In elevation it usually ranges from sea level to about 900 m (3,000 ft) but has also rarely been seen as high as 1,500 m (4,900 ft).
The white-necked jacobin's movement pattern is not well understood. It apparently moves seasonally as flower abundance changes, but details are lacking.
The white-necked jacobin feeds on nectar at the flowers of tall trees, epiphytes, shrubs, and Heliconia plants. Several may feed in one tree and are aggressive to each other, but they are otherwise seldom territorial. Both sexes hawk small insects, mostly by hovering, darting, or sallying from perches.
