04-05: On Non-Native Birds in the ABA Area with Peter Pyle

Of the 1116 species on the ABA checklist, around 50 are what we classify as “non-native”. These are species from other parts of the world introduced either to the North American mainland or, frequently, to Hawaii. The ABA has always tried to keep track of those non-native species through our checklist committee, and whether or not these populations can be counted on an ABA list is always a hot topic. ABA Checklist Committee chair Peter Pyle of the Institute for Bird Populations at Point Reyes, California, joins host Nate Swick to update birders on the status of many of these populations, and the weird circumstances that bring them to North America.
