Violet-Green Swallow (m)
Violet-green Swallows are only found west of the Continental Divide. Take a look at the bird's back, pictured above, to see how they get their name. When they are flying you can easily identify them by the white patch on the bird's rump which shows clearly.
Since swallows are insect eaters, the weather has to be warm enough for their food supply to be available, a sure sign of the advancing year. The two swallows immediately above are both male Tree Swallows. Tree Swallows have iridescent deep-blue backs, white under parts and the long curved wings which all swallows have enabling them to fly far and high in search of hatching insects. All the swallows are superb on the wing. Watch them manoeuvre overhead as the spring days lengthen.

Barn Swallows nest communally in mud nests under the eaves of buildings or lakeside docks. In addition to the curved wings we've already seen, they have a long forked tail which aids their aerodynamics. Look how sleek the bird is when seen from above. They are also very beautiful, with rich colour on face, back and front. Swallows are nature's mosquito repellent!
