Telling the Swift and Swallow and House Martin apart comes down to differences in size, appearance, habitat and voice. Compare them side by side below, or open each species for the full profile.
Apus apus
| Length | 16-17cm |
| Wingspan | 38-40cm |
| Weight | 38 g |
| Family | Apodidae |
| Status | Least Concern |
Appearance
Plumage is blackish brown and the wings make a distinctive anchor shape when in flight. There's a pale patch on the throat and the tail is short with a forked end. Juveniles appear quite similar to adults, but the white throat is more vivid, the wing feathers are pale-edged, and the forehead may appear pale.
Habitat
Spends most of its time in the air and is flexible according to where food is abundant and where the weather is least challenging. In the region it prefers to nest in man-made structures such as churches and lofts.
Voice
Has a high-pitched 'screeee', often heard as birds chase each other.

Hirundo rustica
| Length | 17-21cm |
| Wingspan | 32-34.5cm |
| Weight | 18 g |
| Family | Hirundinidae |
| Status | Least Concern |
Appearance
The Swallow has a wide-based bill, tail-streamers (male's usually longer than female's in spring), and a distinctly forked tail which is spotted white beneath. Plumage is shiny bluish black on top, white underneath, except for a darkish band across the chest and reddish-brown throat and sections of face. Juvenile birds have shorter tail-streamers than adults, and they are paler and more matte.
Habitat
Prefers expansive countryside and generally avoids villages and other largely populated areas. It is a flexible feeder, going to whatever areas offer up the most food; this may be lowland or upland and ranges from water to areas in close proximity to cattle.
Voice
Has a piercing 'tsvit' call, often sounded during flight or when it feels threatened. Male has a fast warble, most commonly heard from a perch close to his nest.
