Range Map Key


Range maps found under each species are based on map graphics from the TOS Handbook of Texas Birds (2014). The species accounts in the TOS Handbook are more specific and the maps more detailed. The hard copy reference book is recommended for a clear understanding of the status and distribution of Texas birds.

Below is a key to understanding the range maps on this site. Maps indicate the typical range of each species in Texas.

Review Species Maps

The following maps are county designations where TBRC Review Species have been documented. These maps do not show the total number of observations as there can be multiple observations in a single county. They show only that a review species has been observed at least once in the designated county.

 
     Ducks - Rails


A Review Species, in general, includes birds that have occurred four or fewer times per year anywhere in Texas over a ten-year average. 

A complete list of review species with the total numbers of reviewed observations can be found at the TBRC website.

For more information on the TBRC bylaws, membership, and meetings, visit the TBRC website.

Some pelagic species are identified offshore and are marked with the closest known county.
