Taxonomy
Subspecies
There are 5 subspecies[1]:
- T. o. pusillus:
- T. o. intermedius:
- Cozumel Island and Holbox Island (off Yucatan Peninsula)
- T. o. ravidus:
- Isla Coiba (Panama)
- T. o. olivaceus:
- T. o. bryanti:
The scientific name has been spelled olivacea in the past.
Habitat
Rain forest, open grassy areas, woodlands and grassland. Observed at heights around 275 meters.
Behaviour
Diet
They feed mainly on seeds (mostly grass), berries and some insects.
Breeding
The female builds the globular nest, which is formed from stems of grass and weeds. They sometimes nest in loose colonies. The clutch consists of two or three brown-speckled white eggs, which are incubated by the female alone for 12-14 days to hatching.
Vocalisation
Call: a weak buzzing trilled ttttt-tee
The male vibrates his wings as he sings to the female from only a few centimetres away.
