Geography
Country: Venezuela


Coordinate: 10° 31' N, 66° 54' W
Coordinate basis: stated in text

Geography comments: coordinate given as "10º30'36" - 66º53' 92"W

Environment
Habitat: tropical/subtropical dry broadleaf forest

Altered habitat: fragment

Substrate: ground surface

WMT: 27.0

CMT: 19.0

MAP: 750.0

Habitat comments: "a 2ha patch of semi-deciduous, seasonal, premontane forest... The vegetation is secondary"
precipitation ranges from "500 to 1000mm per year and an annual temperature between 19 and 27ºC" (presumably meaning monthly means)

Methods
Life forms: birds

Sampling methods: no design,mist nets

Sample size: 133 captures or sightings

Years: 2013, 2014

Days: 10

Seasons: wet or monsoon

Nets or traps: 8

Net or trap nights: 80

Sampling comments: "The study covered the end of the 2013 wet season (September-October), the following dry season (December 2013-April 2014) and the beginning of the 2014 wet season (May-July)... Eight mist nets (12x2.8, 36mm mesh) were... placed twice a month from September 2013 to July 2014. The mist nets were opened from 6:30 to 15:30"
total wet season sampling effort is therefore 2 days x 5 months = 10 days
counts are of captures
