Polyborinaeとは 意味・読み方・使い方

Polyborinae is a subfamily of the falcon family, Falconidae. It contains the caracaras, forest falcons, and Laughing Falcon. All species in this subfamily are native to the Americas. The composition of Falconidae is disputed, and Polyborninae is not featured in the American Ornithologists' Union checklists for North and South American birds. The Check-list of North American Birds considers the Laughing Falcon a true falcon (subfamily Falconinae) and replaces Polyborinae with Caracarinae and Micrasturinae. On the other hand, the Check-list of South American Birds classifies all caracaras as true falcons and puts the Laughing Falcon and forest falcons into the subfamily Herpetotherinae.
