(Redirected from Rhynchostruthus)
The 'Golden-winged Grosbeak' is an attractive, chunky, medium-sized, robust-billed
finch endemic to the southern Arabian and Somalian regions, specifically
Socotra Island, northern
Somalia,
Dhofar in
Oman, and the mountains of north
Yemen to
Saudi Arabia as far north as Al Hara near
Ta'if. It is the only member of the genus ''Rhynchostruthus''.
It can be found in ''
Juniperus procera'' in Somalia and south-west Saudi Arabia, mixed ''
Euphorbia'' and ''
Acacia'' species in Yemen, and it is the fruit of these species that appear to form the bulk of its diet.
The large bill suggests a relationship with the Asian grosbeaks e.g. ''
Mycerobas'' but its song and calls are reminiscent of
European Goldfinch ''Carduelis carduelis'',
European Greenfinch ''C. chloris'', and
Yemen Linnet ''C. yemenensis''. Also it has been observed performing a greenfinch-like slow-winged display flight which suggests its true affinities may lie within the genus ''
Carduelis''.
There are three races:
★
★ ''Rhynchostruthus socotranus socotranus'' - endemic to Socotra.
★
★ ''Rhynchostruthus socotranus percivali'' - southern Arabia.
★
★ ''Rhynchostruthus (socotranus) louisae'' - Somalia. A rather distinct race sometimes treated as a full species.
