vaux swifts with falcon

In the fall swifts congregate in large groups as they prepare for their migration southward to Central America and Venezuela. During September large groups of swifts pass through the Portland-Vancouver Metropolitan region. It is not uncommon for these migrating swifts to use chimneys to roost in during the night and once a population of swifts locates an appropriate chimney they are likely to return year after year. Groups of roosting swifts can range in size from just a few individuals to as many as 35,000 in some larger smokestacks. Chapman School in Northwest Portland houses the larges known roost of migrating swifts in the world! Typically the swifts will only stay a couple of weeks before continuing their migratory journey.This peticular evening had added excitment with the help of a hungry Falcon.
