Common Mistakes

Frequently Asked Questions
It is a hyphenated compound noun. The hyphens link 'rough' and 'winged' to form a single modifier for 'swallow'.

In parts of the Americas, it can be seen near water and open areas, but it is not typically a 'backyard feeder' bird like sparrows or robins.
The exact function is not fully understood, but it is hypothesized the serrations may produce sound during flight or aid in tactile sensing.
