DescriptionIt is bright green with a blue throat and vent and a small bill, quite unlike those of other broadbills. Adults have finely black-streaked buff crowns and narrow black eyestripes.[2] Habitat and rangeIt occurs in tropical moist montane forest, and is endemic to the Albertine Rift Mountains of the Democratic Republic of Congo and Uganda. In Uganda it is a rare resident at 2,100 to 2,200 metres in the Bwindi Impenetrable Forest.[5] Density is probably less than one individual per km2.[1] DietGrauer's broadbill feeds on seeds and fruit, flowers and flower buds, and some invertebrates.[1] StatusThis species is rare, but currently protected only in part of its range. It is threatened by deforestation and habitat degradation, particularly as its currently known distribution overlaps with areas that have seen massive human population influxes in the recent past. It has been classified as vulnerable by the IUCN.[1] References1. ^1 2 3 {{IUCN|id=22698719 |title=Pseudocalyptomena graueri |assessor=BirdLife International |assessor-link=BirdLife International |version=2013.2 |year=2012 |accessdate=26 November 2013}} 2. ^1 2 {{cite journal|last=Rothschild|first=H.|year=1909|title=Description of a new bird from Africa|journal=Ibis|volume=51|issue=4|pages=690–691|url=https://archive.org/stream/ibis39brit#page/690/mode/1up|doi=10.1111/j.1474-919x.1909.tb05277.x}} 3. ^{{cite book |editor1=Andy Purvis |editor2=John L.
