Photograph by Ken High Little Blue Heron Egretta caerulea (Linnaeus) Status: The Little Blue Heron is an uncommon transient and summer resident. Populations have been increasing rapidly since 1980. Period of Occurrence: Record dates are 2 March and 19 December, but the average dates of arrival and departure are 6 April and 5 October. This species was for- merly a postbreeding wanderer but is now a summer resident. Numbers are augmented in late summer by arrivals from farther south. Breeding: This heron has become a regular breeding bird since 1952. A large colony nests primarily in Black Willow trees on the edge of Hutchinson, Reno County. A recent colony has formed on the south edge of Wichita, Sedgwick County, and it is the largest heronry in the state. Several hundred Little Blue Herons nest there in a tree nursery. There are undoubtedly more undiscovered colonies in the state. A colony in Harper County moved after one year and has not been located again, although large numbers of birds have been seen in the area. Nests are usually placed in low shrubs, trees, and cattails. The nest is a typical heron nest made of sticks and is often destroyed by gale-force winds. The herons usually lay four to five eggs, but there.
