What is the airspeed velocity of an unladen swallow?<|im_end|>
<|im_start|>assistant
The airspeed velocity of an European unladen swallow has been approximated to be about 24 miles per hour or 11 meters per second. This was achieved by performing mathematical calculations based on body mass and wing length of the bird. A more accurate answer requires further experimentation.<|im_end|>

<|im_start|>assistant
The most common swallow species found in North America are:

-   Barn swallow - Widely distributed across North America, with blue upperparts and orange-brown underparts.
-   Cliff swallow - Builds large mud nest colonies on cliffs, under bridges or buildings. Has a squared-off tail and blue-black upperparts.
-   Tree swallow - Breeds across much of North America. Has iridescent blue-green upperparts and white underparts. Nests in tree cavities 
     or nest boxes.
-   Bank swallow - Nests in burrows in sandy banks, has a brown back and white underparts.
-   Rough-winged swallow - Similar to bank swallow but with feathered wing edges. Nests in burrows or under bridges.

These are the primary swallow species found across North America. There are a couple of other less common or more localized species as well. 

Regarding their speed, swallows are extremely agile and fast flyers. Their average flying speed is around 11 miles per hour (18 kph). However, they are capable of much greater speeds when chasing insects or migrating. Barn swallows have been clocked at over 30 miles per hour (48 kph) during migration. Cliff swallows have been recorded at over 50 miles per hour (80 kph) while chasing insects. Their incredible flying skills, speed, and agility allow swallows to catch insects on the wing and perform amazing aerial maneuvers.<|im_end|>
