(Eriocaulaceae). (3) Wet grasslands, dominated I 
Lagenocar/ius rigidus in marshy areas close 
watercourses. (4) Dry scrubland, which has son 
plants that also occur in the rocky outcrop habit: 
but which is dominated by Coccoloba acrosi 
choides (Poligonaceae) and Aulonemia effic 
(Poaceae) in sandy soil with substantial gravel 
some hilltop areas. (5) Wet scrubland, dominate 
by small trees up to 2 m in height, such ; 
Tibouchina spp., Lavoisiera imbrkata (Melasti 
mataceae), and Baccharis ilatiaiae (Asteraceae) i 
marshy areas. (6) Riparian woodlands, charactei 
■zed by dense vegetation and dominated by 4 t 
10-m tall trees including Miconia chartace, 
(Melastomataceae) and Hololepis peduncular 
(Asteraceae). (7) Candeial , a specific formatioi 
of dense groups of 3 to 5-m tall Eremanthm spr 
(Asteraceae) trees, known as ‘candeia’. The tern

We captured Serra Finches using mist nets and 
banded each with unique combinations of colored 
leg bands to allow individual identification and 
numbered metal leg bands supplied by Centro 
Nacional de Pesquisa para Conserva^ao de Aves 
Silvestres (CEMAVE/IBAMA. license # 1161/3 
and I 161/5). Surveys were conducted throughout 
the study area. Locations of Serra Finches were 
recorded using a hand-held Garmin (Olathe. KS 
USA) global positioning system (GPS) unit lo 
within 9 m accuracy. All GPS locations corre¬ 
spond to pairs because finches were always 
detected in pairs. Locations were recorded every 
H> m of a pair's movements (not caused by 
observer presence) until lost from view. Habitat 
type was recorded where birds were observed. 
Territory Distribution.—We took GPS loca¬ 
tions lor all marked and unmarked pairs detected 
in the study area. Pairs were detected mainly 
while singing a duet from a perch, which was 
interpreted as evidence of a particular mated 
pair's territory. Locations were recorded through¬ 
out the year (dry and wet seasons), as we did not
