First biologging record of a foraging Red-Throated Loon Gavia stellata shows shallow and efficient diving in freshwater environments
Recently, Red-throated Loons Gavia stellata (RTL) have been the subject of increased interest due to their negative interactions with shipping, offshore wind farms, and other marine industry activities. This has driven a desire to quantify the behaviour and ecology of this understudied species, part...
