About These Birds
Common Myna
The common myna has been named one of the world's 100 worst invasive species by the IUCN. Originally from South Asia, it has been introduced to tropical regions worldwide where it outcompetes native birds for nest cavities. Despite its invasive status, the myna is an intelligent and charismatic bird capable of mimicking human speech.
Downy Woodpecker
The downy woodpecker is the smallest and most widespread woodpecker in North America. Its small size allows it to forage on thin branches and weed stems that larger woodpeckers cannot access. Downies often join mixed-species flocks in winter, benefiting from the extra vigilance of multiple species watching for predators.
