I have talked about the European Oligocene epoch and its birds with brittly limbs before.
Here’s another such brittle-limbed bird from the early Oligocene of Europe, this one has lost its wings, or at least one wing, literally … it is known from parts of the right wing.
The most interesting fact in this case is, the bird belonged to a group of birds that are part of the Passeriformes but aren’t songbirds, these are called suboscine birds.
The whole group of suboscine birds is now restricted to, well, it’s actually occurring worldwide, especially in South America, but it is not found in Europe today.
The bird appears to have been of similar size to the Sunbird Asities (Neodrepanis spp.), which today inhabit the island of Madagascar (… these are suboscine birds as well, by the way).
