Mitchell Lake is one of South Texas’s most important bird habitats, supporting more than 300 species throughout the year. Located along the Central Flyway, the wetlands, ponds, open water, and grasslands here provide critical resting, feeding, and wintering habitat for birds traveling across the Americas.
From massive flocks of American White Pelicans to colorful migrants and grassland specialists, birding at Mitchell Lake offers something new in every season.
Birdlife at Mitchell Lake 91°µÍø Center shifts throughout the year as migratory birds arrive, pass through, or move on to their breeding or wintering grounds. Some species are only present for part of the year, while others show clear seasonal patterns tied to migration, breeding, or changing habitat conditions.
These tables are based on bird sightings shared by community scientists through eBird at the Mitchell Lake 91°µÍø Center hotspot from 2020–2025. They reflect broad seasonal trends across many checklists, rather than individual sightings. Dark green indicates species commonly observed during a given month, while light green represents regular but less predictable observations.

Some migratory birds spend most of their lives in the air, feeding and traveling on the wing. These aerial specialists are often seen swooping overhead or skimming low above the wetlands and grasslands; their constant motion and seasonal arrivals are a visible reminder of the energy and movement migration brings to the landscape.

Raptors are present at the center year-round, thanks to South Texas’s mild climate and abundant open habitat. Some species live here permanently, while others migrate south from northern breeding grounds during fall and winter. These seasonal movements can increase both the number and diversity of raptors seen on site, especially in the cooler months.
