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: 98 captures or sightings
Years: 2013, 2014
Days: 10
Seasons: dry
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 dry season sampling effort is therefore 2 days x 5 months = 10 days
counts are of captures
