Forest Robins, Stiphornis spp (1 Viewer)

I'm in Gabon at the moment and I hope someone has any info on the taxonomy of Forest Robins as the other 3 birders with me all have differing opinions. Are there 1, 2 or 4 bl**dy species. Please help as the cost of a weeks beer rests on this!

As usual, that depends on who you believe:

Clements: 1 species
IOC: 5 species
ABC: 1 species

Thanks Niels + Sally.:t: It looks like we'll all be buying our own beers.:C:C The two taxa we've seen here, in the north, appear to be sympatric, look very different and some vocalisations could differ, so we'll have to leave them as Forest Robin ???????????????? "thingies".

In the older versions of IOC, the ranges are listed for each one that now would be a subspecies:
erythrothorax: W Africa
pyrrholaemus: SW Gabon
gabonensis: WC Africa
xanthogaster: C Africa
sanghensis: Central African Republic

As I read this, several of these could occur in Gabon. Make notes for determination of which subspecies, your observations sound like the last word has not been spoken in this case.

Hi Chris,

Three of the (sub)species apparently occur in Gabon:

These are gabonensis in the north and north-west, xanthogaster in the north-east and pyrrholaemus in the south-west.

See the map in Schmidt et al (2008) A new species of African Forest Robin from Gabon (Passeriformes: Muscicapidae: Stiphrornis). Zootaxa 1850:27-42.

The pdf of this paper can be found at http://www.mapress.com/zootaxa/list/2008/zt01850.html

Thanks for the gen Shaun. Just got back to Libreville from Moukalaba-Doudau NP where we saw at least 3 birds fitting the description ( very different from the other two taxa, in the north and more like Sanighe Forest Robin in Sinclair and Ryan, but even more olive upperparts).

Voelker G., Tobler M., Prestridge H.L., Duijm E., Groenenberg D., Hutchinson M.R., Martin A.D., Nieman A., Roselaar C.S. & Huntley J.W., in press. Three new species of Stiphrornis (Aves: Muscicapidae) from the Afrotropics, with a molecular phylogenetic assessment of the genus. Syst. Biodivers.

Abstract: We describe three new species of forest robin in the genus Stiphrornis; two from West Africa and one from the Congo Basin. Each species represents a distinct phylogenetic lineage based on genetic analysis. In addition to genetic differentiation, each new species is diagnosable from other Stiphrornis lineages by morphology, and by plumage. One of the new species appears to be restricted to the Central and Brong-Ahafo Regions of Ghana, and another is restricted to Benin and the Central Region of Ghana. In Ghana, these two new species presumably come into contact with Stiphrornis erythrothorax (Western Region of Ghana and westward), and there is evidence that one of the new species has a distinguishably different song from erythrothorax. The distribution of the third new species is primarily on the south bank of the Congo River, near the city of Kisangani. Recognition of these species provides additional evidence that Afrotropical forests are harbouring substantial cryptic diversity, and that our knowledge of the drivers of this diversity remains poorly documented across the region.

Very interested if anyone has access to a copy of this. Possible trip to Ghana next year. *fingers crossed*
