A research project investigating migratory insect-bird interactions, bioflow and dragonfly migration. Lund Univ. & Univ. of Exeter


Apparently, when on migration, Chuck-will's-widow (a nightjar), switches from insects to a diet of co-migrant songbirds. And swallows them whole! - as described in this account fr 1899 from a steamer outside S Carolina, or by Owre 1966, as he disected one found dead in Florida


A Pair of Tawny Coster (Acraea terpsicore) butterflies from the Maldives. These mimics of Danaus butterflies could be migratory, perhaps crossing the Indian Ocean! Our (@JSUHedlund @zanderhayward @EcosystemsInSky) research could reveal more soon! So exciting! #insectmigration

📢NEW PAPER! Authored by the CEC's Richard Massy & Karl Wotton @KoralWotton on the efficiency of various modes of time compensation for the movement of the sun during migratory journeys. Biology Letters (2023) doi.org/10.1098/rsbl.2… Photo Credit: @WillLeoHawkes




!!! This is a windowed carpenter bee, Xylocopa fenestrata. With his blue eyes matching the Maldivian sea! They also have a very interesting distribution right across the Indian Ocean... Perhaps a migrant too? @zanderhayward @JSUHedlund
