Cormorants are those birds that look like mini Loch Ness Monsters, the ones you see swimming in the water with just their head, neck, and a tiny bit of their back out. They stand upright when on land.
Baby birds are freaky-lookin’ things already when they aren’t baby waterbirds. These guys are just piling it on.
Cooperation among different species of birds is common. Some birds build their nests near those of larger, more aggressive species to deter predators, and flocks of mixed species forage for food and defend territories together in alliances that can last for years. In most cases, though, these partnerships are not between specific individuals of the other species—any bird from the other species will do.
But in a new study published in the journal Behavioral Ecology, scientists from the University of Chicago and University of Nebraska show how two different species of Australian fairy-wrens not only recognize individual birds from other species, but also form long-term partnerships that help them forage and defend their shared space as a group.
“Finding that these two species associate was not surprising, as mixed species flocks of birds are observed all over the world,” said Allison Johnson, Ph.D., a postdoctoral scholar at the University of Nebraska who conducted the study as part of her dissertation research at UChicago. “But when we realized they were sharing territories with specific individuals and responding aggressively only to unknown individuals, we knew this was really unique. It completely changed our research and we knew we had to investigate it.”
The Sri Lankan junglefowl is a member of the Galliformes bird order which is endemic to Sri Lanka, where it is the national bird. It is closely related to the red junglefowl (G. gallus), the wild junglefowl from which the chicken was domesticated. As with other junglefowl, the Sri Lankan junglefowl is strongly sexually dimorphic: the male is much larger than the female, with more vivid plumage and a highly exaggerated wattle and comb. As with other jungle fowls, Sri Lankan jungle fowls are priliminary
aTerrestrial animal. It spends most of its time foraging for food by
scratching the ground for various seeds, fallen fruit and insects.It is common in forests and scrub habitats, and is commonly spotted at sites such as Kitulgala, Yala and Sinharaja.
