This dataset has been requested for 'the Horizon e4Warning project on mapping and modelling West Nile Virus Disease and its Hosts' then been downloaded from ebird.org and it includes weekly abundance geospatial tifs for for 2021 and 2022 for 23 species: weekly presence weekly species richness week abundance sum Data obtained from Ebird https://science.ebird.org/en/status-and-trends/species/ Species Names: Species English Name filname code Alcedo atthis Common Kingfisher comkin1 Anas platyrhynchos Mallard mallar3 Anser anser Graylag Gose gragoo Athene noctua Little Owl litowl1 Bulbulcus ibis Cattle Egret categr Buteo buteo Common Buzzard combuz1 Columba palumbus Commin Wood Piegon cowpig Corvus cornix Hooded Crow hoocro1 Corvus corone cornix Carrion Crow carcro1 Corvus monedula Eurasian Jackdaw eurjac Cyanistes caeruleus Blue Tit blutit Egretta garzetta (Little Egret) litegr Eremophila alpestris Horned Lark horlar Falco tinnunculus Eurasian Kestrel eurkes Garrulus glandarius Eurasian Jay eurja1 Hirundo rustica Barn Swallow barswa Larus argentatus Herring Gull hergul Lulua arborea Woodlark woolar1 Luscinia Luscinia Thrush Nightinglae thrnig1 Luscinia megarhynchos Common nightingale comnig1 Passer domesticus (including Passer italiae and Passer hispaniolensis) House Sparrow houspa Pica pica Eurasian Magpie eurmag1 Streptopelia decaocto Eurasian Collared Dove eucdov Turdus merula Eurasian Blackbird eurbla File Names: a) e4ebirdwnvhostsweeklyabundance all weekly abundance datasets at 3km resolution. b) e4ebirdwnvhostweeklyPA abundance with missing recoded to 0. This is based of ad hoc checks of weekly datasets against the birdlife species ranges, which suggest that the maximum extents of combined weekly abundance distributions match the rage boundares fairly well c) e4ebirdspprichnessallSUMMEANweekly summed and mean weekly presence absence for all species. If a species in missing a weekly dataset it is removed from the Mean value calculations for that week. To maintaing a constant maximum presenxe number in the summed number of present species, missing weeks are filled with last valid presence week up to halfway through the gap in availability, then with the first avaiklable distribution after the gap d) calcsumabundallweeks weekly sum of abundance of 23 spp. As there qare some gaps for various species this is an interim product.. When divided by the nunber of species summed (see below) it provides an index of collective abundnace of the 23 host spp e) meanallabundallweeks weekly summed abundnace divided by number species summed (acounts for gaps indata) . Only NOData if no species recorded
