As an eBird reviewer, I flag exotic species that aren't widely established so they aren't visible on eBird outputs. As a birder, I sometime regret this. Here's an example, a lovely Red-lored Parrot that we first identified in flight as a Red-crowned Parrot, but a closer look revealed the yellow cheek and the blue crown. This bird was in Laredo at Slaughter Park, and others had more Red-lored and even some Yellow-headed Parrots at this very birdy site. Thanks to Teresa K for the photo!
