Populations of invasive species that colonize and spread in novel environments may differentiate both through demographic processes and local selection. European starlings (Sturnus vulgaris) were introduced to New York in 1890 and subsequently spread throughout North America, becoming one of the most ...

But a recent paper found that sleeping European starlings (a common bird found in North America and Britain) don't use the mechanism. The researchers observed that the birds' feet their knees only slightly, not enough for the mechanism to kick into action. The toes as a result, were never...
In New Zealand, the Starling was introduced in 1862, and now occurs in most of the country. North America Although there are approximately 200 million starlings in North America, they are all descendants of approximately 60 birds (or 100 [1]) released in 1890 in Central Park, New York, by...
Structure distinctive, but sometimes confused with unrelated blackbirds, which often co-occur with starlings in large flocks. Blackbirds more slender bodied, with longer tails and less-pointy wings. Flight profile more like a waxwing’s or a meadowlark’s than blackbird’s. Voice Highly vari...

this navigation was demonstrated by shifting the light: dark cycles of the hive by 6h (or 90° of the 24h day) and showing that the bees consistently make a 90° error in orientation. This capacity has also been demonstrated in several species of birds, including European starlings and ...
