Habitat comments: "in the Abobral sub-region of the Pantanal" and specifically within (forest patches (capóes), 1-2 m above the seasonally flooded landscape... The studied area lies in the center of a cattle farm" but these are forest fragments (maximum size 4.8 ha), not pastures
MAT 27º C in the rainy season (November to March) and 20º C in the dry season (April to October)
MAT 27º C in the rainy season (November to March) and 20º C in the dry season (April to October)
Methods
Life forms: birds
Sites: 7
Sampling methods: line transect, mist nets
Sample size: 175 captures or sightings
Years: 1999
Days: 14
Net or trap nights: 124
Basal area status: not applicable
Sampling comments: study was in seven forest patches, three > 1 ha and four < 1 ha
"I banded birds for 14 days (two days per patch) in January, February, April, and September 1999, in the same patches where I carried out observations. I used 6 m long by 2.6 m high mist-nets, with 36 mm mesh size, opened for 5 h since sunrise... The number of nets used varied with patch size: 20 nets in patches > 1 ha (10 in the interior and 10 at the edge) and 16 nets in patches < 1 ha (eight in the interior and eight at the edge)" so there were 10 nets x 3 patches x 2 days = 60 net days in large patches in this habitat and 8 nets x 4 patches x 2 days = 64 net days in small patches
nets were placed in rows
