Flocks of migrating Jays move through this district on their northward flight from the 15th of April to the 5th of May and on the southward journey during the first half of October.  A route much used by these migrants is along the Missouri bluffs and lowlands.

     During some winters Jays are to be found in numbers, even in the city, but during others are very scarce.  During the rather severe winter of 1916-1917, few Jays were to be found anywhere but in Swope Park.

     Jays nest early in May and more than one brood is raised.
