A Great Grey Shrike Lanius excubitor (ssp. leucopygos or elegans) photographed on the island of Pecixe, Guinea-Bissau, well south of its known range, on 20 November 2017, is apparently the first for the country (Fig. 21; GC); L. e. leucopygos and L. e. elegans were previously included in Southern Grey Shrike L. meridionalis, but molecular studies suggest that the latter taxon is monotypic and that African taxa belong to the widespread L. excubitor (cf. del Hoyo, J. & Collar, N. J. 2016. HBW and BirdLife International Illustrated Checklist of the Birds of the World. Vol. 2.).

During field work conducted in the Boe area, in the south-east, in January - February 2013, some 170 bird species were identified, including three that appear to be new for the country: Chestnut-backed Sparrow Lark Eremopterix leucotis, Lesser Striped Swallow Cecropis abyssinica and Heuglin's Wheatear Oenanthe heuglini. Two more, Flappet Lark Mirafra rufocinnamomea and Dybowski's Twinspot Euschistospiza dybowskii, are not mentioned in the ABC checklist of Guinea-Bissau (Dowsett et al. 2013) either, although they are listed for Vendu Tcham, an Important Bird Area to the east of Boe, in Dodman et al. (2004. Important Bird Areas in Guinea-Bissau). Other noteworthy species observed include Red-thighed Sparrowhawk Accipiter erythropus, Black-throated Coucal Centropus leucogaster, Shining-blue Kingfisher Alcedo quadribrachys, Chestnut-breasted Negrofinch Nigrita bicolor and Red-winged Pytilia Pytilia phoenicoptera.
A male Collared Flycatcher Ficedula albicollis in full breeding plumage was watched at close range in Bijagos Archipelago National Park, Orango Island, on 27 February 2005. This constitutes the first for the country and also the first definite record west of Nigeria / Niger.
Wetlands International coordinated a number of surveys in Guinea-Bissau between 2000 and 2003, mainly focused on waterbird and IBA surveys. Several new species to the country were added, and these are all included in the country species list (DODMAN, T. et al 2004). Scientific papers will be prepared to document the dates and circumstances of these and other noteworthy sightings in 2005.
