Stop, it's hummer time!. Leucistic Anna's Hummingbird
Get your binoculars and field guide and head to a local park to spot a hummingbird! Birds come in a wide range of shapes, sizes, colours and behaviours, making them one of the most diverse groups of animals on Earth—from imposing eagles to today's tiny snowy-winged star, a leucistic Anna's Hummingbird. These hummingbirds are typically vibrant in colour, but leucism means that they have decreased pigmentation, resulting in a paler appearance. Unlike albino birds, these hummingbirds retain some colour in their eyes. They are equipped with specialised adaptations like a long tongue for feeding on nectar from flowers. However, their diet is not limited to nectar alone; they also supplement their nutrition by consuming small insects and other arthropods. Their lighter plumage reduces protective camouflage, making them more vulnerable to predators such as hawks and feral cats.
