Checklist for Birds in the Lower Rio Grande Valley Prepared by Quinta Mazatlan World Birding Center in McAllen, Texas Thanks to thousands of people sharing their sightings, the bird community of the Lower Rio Grande Valley (LRGV) is at a whopping 512 species – a species richness larger than all but 6 states! The amazing diversity of birds found in the four-county region (Cameron, Hidalgo, Starr, and Willacy) is made even better by the presence of South Texas Specialty Birds – birds that are found almost nowhere else in the United States. This checklist was created using data from eBird, run by the Cornell Lab of Ornithology. There is an important consideration for eBird: the data depends on people – who was birdwatching, where they were, and what they were looking for. Generally, there is a bias for more checklists to be submitted from urban regions; the more people, the more likely there are to be eBird reports. Another thing to consider is that birdwatcher skill varies; some people have more experience than others. Lastly, and most important for this checklist, is that birdwatchers like to see rare or unusual birds – they even “chase” them across states! Birders specifically traveling and searching for one bird can create a skew in eBird frequency data. For example, if you look at the winter frequency of Blue Bunting and Indigo Bunting in this checklist, they appear to have similar frequencies. However, there are only 52 records of Blue Bunting in the United States, whereas Indigo Bunting is a much more abundant species. Remember, this checklist is about how often birds are reported by eBird observers. LEGEND Symbol
