Notes On Bird Species In Bamboo In Northern Madre De Dios, Peru, Including The First Peruvian Record Of Acre Tody-Tyrant (Hemitriccus Cohnhafti)

Noteworthy records of birds from Pando including two new species for Bolivia

“…The species is poorly known ecologically, having been described only recently from Acre, Brazil (Zimmer et al . 2013), where it was first found in 2011, and subsequently was reported in Amazonian Peru (Harvey et al . 2014).…”

“…The species' current presence there may also be due to recent deforestation, as in 2018 the locality was characterised by intact forest with a bamboo understorey. It seems to prefer extensive and perhaps partly decaying Guadua without a forest canopy (Harvey et al . 2014) and may opportunistically appear at sites with suitable early-succession, bamboo-dominated habitat.…”

The species is poorly known ecologically, having been described only recently from Acre, Brazil (Zimmer et al 2013), where it was first found in 2011, and subsequently was reported in Amazonian Peru (Harvey et al 2014).…”

On 30 September 2022, we found the species between San Miguel de Machineri and Estancia Porta Atenda, near the floodplain of the Acre River, at 10°57'15.84"S, 69°28'9.84"W, at 08.07 h. The area was also characterised by extensive and decaying Guadua with scattered secondary woody growth, and is <1 km from the Brazilian border and c.60 km north-northeast of the first locality.…”
