Little Blue Heron
Egretta caerulea
Until recently, we believed Little Blue Herons only bred from the Gulf states of the USA through Central America and the Caribbean south to Peru and Uruguay. But since the 1980s, we can find them year-round in San Diego.
During their first year, the Little Blue Heron is white, which seems to help it blend in with groups of Snowy Egrets these younger birds often associate with. As it begins its second year, it develops blue-gray blotches. We call this the calico phase. As an adult, its blue-gray and purple coloration gives it a striking appearance. During the early 20th century, when the millinery trade nearly exterminated many of the white herons and egrets so ladies could have pretty hats, they spared the Little Blue Heron because their dark feathers were not in demand.
Given the wide range for this species, and the mix of migratory and sedentary populations, it seemed likely science would split Little Blue Heron into multiple subspecies. However, my research showed scientists consider them to be monotypic (i.e. no subspecies).
Naturally, my first encounters with Little Blue Herons occurred in my hometown of San Diego. But my visits to Texas in 2020 and 2021 provided me with some wonderful meetings as well.

Description: The views of waders at the Nature Center were generally more satisfying than from the Convention Centre. There are wetlands that the South Padre Island Convention Centre (free access) and the Birding & Nature Center (admission fee required) share. My previous visits to the wetlands had been to the Convention Centre. On this day I would find out why folks pay money to see the marsh, when there is free access next door. |

Description: For most of the time I spent at Hunter Lane, this heron was content to stay into the sun and out of camera range. Luckily, it broke the pattern briefly before I finished my day. Hunter Lane is at the far side of the park, two miles from the Resaca de la Palma Visitor Center. It is the most reliable place in the reserve to find standing water, and my favorite place to enjoy birds. |

Description: Waders I saw on the pond were shy. This Little Blue stayed well away during my visit. I drove this Wednesday to Brazoria National Wildlife Refuge, but found its gates locked, so as a consolation prize, I continued to San Bernard National Wildlife Refuge, where I found birds that hadn’t left Texas yet for the winter. |

Description: I was photographing a Prothonotary Warbler when the Little Blue Heron walked through the scene. With a momentary lull in warbler migration on South Padre Island, I paid my admission to the Birds and Nature Center to attempt catching subjects that don’t make many appearances at the Convention Centre. |

Description: This Little Blue Heron shows a preference for the tall grasses in the marsh. Sunday was a day when the birds and then birders increased their respective presence on South Padre Island. Both are to be expected as spring migration steps up the bird numbers moving through on their way north. |
