Banded Yellow Robin Gennaeodryas placens


Justification of Red List category
This species has a large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (extent of occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is not known but it is considered highly unlikely that the species approaches the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Population justification
The global population size has not been quantified, but the species is described as locally fairly common to common (del Hoyo et al. 2007, Pratt and Beehler 2015, Beehler and Pratt 2016).

Trend justification
There are no data on population trends. Forest cover loss in this species' mapped range has been slow, equivalent to c.2% over the past ten years (Global Forest Watch 2022, based on data from Hansen et al. [2013] and methods disclosed therein). Precautionarily, this is suspected to be causing a slow decline.

Distribution and population

Gennaeodryas placens is very patchily distributed in New Guinea (Papua, Indonesia, and Papua New Guinea). It has been recorded from Batanta Island, Wandammen Mountains, Fakfak Mountains, Kumawa Mountains, Weyland Mountains, Keku near Madang, Lake Kutubu, Mt Bosavi, Karimui, and a number of sites in Central Province (Diamond 1985, Beehler et al. 1986, Coates 1990). There are records from Crater Mountain (A. Mack in litt. 1999), where it is patchily abundant, and in limestone hill forest from Moro to Gobe, Gulf Province, where it is locally common (K. D. Bishop in litt. 1999). It may prove to be more widespread through the central mountains but is believed to be absent from many intervening areas (Diamond 1985). Surveys in the Karimui area did not detect the species, though mist netting was at higher elevations and so this may not be a true absence (Freeman and Freeman 2014).


It is a hill forest species, occurring between 100 and 1,450 m; it is often more common at lower altitudes. It occupies primary forest and frequents shady areas with an open understorey. Cup shaped nests are made up of roots and moss (Pratt and Beehler 2015).


Some parts of its range are impacted by forest loss and degradation, however its predilection for inaccessible areas buffers it from more severe forest loss and there may be more, secure subpopulations yet to be discovered.

Conservation actions

Conservation Actions Underway
None is known.

Conservation Actions Proposed
Conduct searches to discover additional subpopulations. Regularly monitor the population at selected sites. Protect significant areas of primary forest, both at sites where it is known to occur, and more extensively within its known range.
