Occurrence and habits of the Gambaga Flycatcher Muscicapa gambagae in Kenya, including the first description of its song

Abstract

Historically, the Gambaga Flycatcher Muscicapa gambagae has been a relatively poorly known bird in Kenya. Following a review of all known records in Kenya, we show that breeding of presumed resident birds is known from three discreet areas, but that as many as 47% of all records, from the months of October to March, come from areas where breeding is not known. This finding indicates a migratory origin for these individuals, and the concurrent absence of northern, summer-breeding Gambaga Flycatchers from the mountainous regions of western Saudi Arabia, Yemen and northern Somalia point to that region as a likely origin of these winter visitors. Furthermore, records show that the frequency of occurrence of the Gambaga Flycatcher in Kenya is also increasing, with a rate of reporting since 2000 which is four times higher than during the period 1960–2000, likely representing a shift in range. Lastly, we also describe some habitat characteristics at preferred sites, and provide the first published sonograms and accompanying description of the song.
