Our paper about the flow of nocturnal bird migration through Colombia is finally out today in #ProcB! Using weather radars operated by the #IDEAM, we found that low variability in wind underlies a pace of migration that is far more gradual than at temperate latitudes. #Ornithology 📡🪶🇨🇴

It's that dreaded time of the year when one has to sort thru Willow and Alder Flycatchers. Primary tip spacing can make one's life much easier as outlined in Andrew Birch's and my article in Western Birds. Photo below from @evornithology.bsky.social static1.squarespace.com/static/54b9b...

The Nechisar Nightjar Caprimulgus solala was described only from a single wing collected as roadkill from Nechisar National Park in Ethiopia in 1990. To resolve its taxonomic status a sample was taken...

Another birding paper! 🐦 Where do the Nearctic landbirds that show up in Europe each autumn come from? We usually assume they come from NE populations, pushed off course by bad weather - but is that the whole story? #ornithology 1/3

Of which the epithet solala means only one wing!
forever flying in circles..
Recent searches on the Nechisar plain to find it have still drawn a blank 🤔

Whenever I hear someone say that ebird data sucks and is unreliable, it tells me that they are repeating something they were told 15 years ago, and that they haven’t read any of the truly groundbreaking methods developments that have made ebird one of the best macroecological datasets on earth
other fun facts I learned today is that ebird data is garbage and too low quality to be used for anything
and spatial products for good abiotic data are not available at resolutions <1km 🫠
News to me!

authors compared modern eBird records to info from historical bird atlas from 1970s to infer distributional changes in Kenyan birds
lots of cool results, including expansions in introduced sp (lots of green on maps below)
admirably concise and clear as well
