Buff-rumped Warbler Myiothlypis fulvicauda



Conservation Status

Not globally threatened, with extensive range through Central and South America. No population estimate known. As an obligate riparian species, loss in riparian habitats could lead to a decline.

Effects of human activity on populations

Known to occur along human habitation, so disturbance does not appear to be an issue. Anecdotal evidence of foraging at a black light sheet during the day to capture insects attracted at night (Sibbald 2015).

Also known to be disturbed by approaching people and passing boats, flushing away and issuing a loud “chip” (Ridgely 1989) This suggests that the bird may be disturbed by high levels of activity on stream habitats in the tropics. Loss of habitat along steams will also lead to a decline of this species.

Studies done on an ecologically-similar stream-loving warbler, the Louisiana Waterthrush (Seiurus motacilla), showed that acid deposition in streams led to lower densities in waterthrush numbers (Sharpe 1999). While there were lower densities of waterthrushes, the reproductive success of the pairs of waterthrushes were not affected, as waterthrushes on polluted streams raised as many offspring as waterthrushes on unpolluted streams. The waterthrushes also changed their foraging strata to include different macroinvertebrates, as some macroinvertebrates had declined. Acid deposition in Neotropical streams may lead to a similar effect, and should be studied further.
