Here we present arrival patterns of some of the most-reported species: the Barn Swallow, Brown Shrike, White Wagtail and Western Yellow Wagtail.

Like in previous summaries each sighting is shown as a vertical black line.

As you can appreciate from the above illustration, Barn Swallows and Brown Shrikes arrive around late July/early August and nearly all of them leave by April. The wagtails normally arrive in early September and usually are gone by April-end. (This summary has only been possible thanks to your contributions!)
