Our objectives were to 1) determine the current density of LEPC leks and LEPCs within the Texas (USA) occupied range, including areas with high potential for wind‐energy development; and 2) find new leks. To estimate lek and LEPC density, we employed a line‐transect‐based aerial survey method using a Robinson 22 helicopter to count leks. We surveyed 26, 810.9 km of transect in the spring of 2010 and 2011 and we detected 96 leks. We estimated a density of 2.0 leks/100 km<sup>2</sup> (90% CI = 1.4–2.7 leks/100 km<sup>2</sup>) and 12.3 LEPCs/100 km<sup>2</sup> (90% CI = 8.5–17.9 LEPCs/100 km<sup>2</sup>) and an abundance of 293.6 leks (90% CI = 213.9–403.0 leks) and 1, 822.4 LEPCs (90% CI = 1, 253.7–2, 649.1 LEPCs) for our sampling frame. Our best model indicated that lek size and lek type (AIC<sub><italic>c</italic></sub> wt = 0.235) influenced lek detectability. Lek detectability was greater for larger leks and natural leks versus man‐made leks.
