White-Bellied Barn Swallow

There are six species of barn swallow and I'd previously blogged on one of them, H. r. erythrogaster, the North American subspecies found at the Bear River Migratory Bird Refuge. It has redder underparts and a narrower, often incomplete, blue breast band. I recently saw the nominate European subspecies, sometimes called the white-bellied barn swallow, H. r. rustica. 
This is the North American barn swallow.

This is the European, white-bellied, barn swallow.
