“…Historically, APCs ranged from southwest Louisiana to possibly near Brownsville, Texas (Lehmann 1941, Oberholser 1974). However, in reviewing historical accounts Lehmann and Mauermann (1963) concluded: "…Attwater's prairie chickens have almost certainly never been abundant in any part of the southern coastal prairie south of the Nueces River from the mid-1800's to the present. "…”

“…APCs were extirpated from Louisiana by 1919 (St. Amant 1959, Lehmann 1965, Oberholser 1974), although St. Amant (1959) reported huntable populations existed in 12 parishes by as late as 1890.…”

“…Historically, fire was an important factor in maintaining the open character of grasslands occupied by APC (Lehmann 1965).

“…Lehmann and Mauermann (1963) described an account of several hundred dead APCs near a cotton field that had been dusted aerially with arsenic (no longer in use) as a defoliant. Flickinger and Swineford (1983) observed that organochlorine, polychlorinated biphenyl (PCB), and metal residues in APCs and northern bobwhites from cropland areas were low.…”

Diet sources of the endangered Attwater's prairie‐chicken in Texas: evidence from δ¹³C, δ¹⁵N, and Bayesian mixing models

et al. 2020

The Attwater's prairie-chicken (APC; Tympanuchus cupido attwateri) was listed as an endangered species in 1967, and since then multiple studies have addressed ecological and human factors that may have limited their population recovery. In this study, we used stable isotopes of carbon and nitrogen (δ 13 C and δ 15 N) in conjunction with Bayesian mixing models to determine current diets of APCs at the Attwater Prairie Chicken National Wildlife Refuge (APCNWR), and to compare them with past diets derived from the isotopic composition of feathers from museum specimens (1894-1965) to help elucidate potential factors limiting APC recovery. We collected feathers, blood, and feces from APCs at the APCNWR, and feathers from museum specimens. In addition, potential food items (vegetation, spiders, and insects) were collected from APCNWR and analyzed for δ 13 C and δ 15 N. A stable isotope mixing model (MixSIAR) was used to determine diet source contribution to past and present APC populations. δ 13 C values in APC blood were significantly greater in the fall than in the summer. Blood δ 15 N values were significantly greater in the summer than in the winter. δ 13 C values in feathers from museum and contemporary APCs were not different, although δ 13 C values in contemporary feathers were enriched by 0.5‰ relative to museum specimens. Results indicated that insects were the predominant food source in the summer and fall (61-65%) and C 3 vegetation was predominant in the winter (64%). Using isotope values from feathers, the model predicted that the predominant food source during the period of feather growth were insects (62%) followed by C 3 plants (17-18%), spiders (12-18%), and C 4 plants (2-3%). Feathers from contemporary birds had δ 15 N values 0.9‰ lower than those from museum specimens, suggesting potential shifts in diets in APCs currently in the wild relative to the past. We hypothesize that the abundance and species richness of various arthropods may have changed at the APCNWR resulting in current APCs in the wild feeding on arthropods with lower δ 15 N values than in the past. Orthopterans comprised about 23% of the APCs diet currently in the wild, while they represented only about 19% in the past.

Detectability of lesser prairie‐chicken leks: A comparison of surveys from aircraft

et al. 2011

Lesser prairie‐chickens (Tympanuchus pallidicinctus) are traditionally monitored by spring road‐based lek surveys and counts of males attending leks. Several weaknesses exist with ground‐based monitoring methods such as the bias of restricting surveys to roads, unknown probability of lek detection, and man‐hours required to survey large tracts of habitat. We evaluated aerial surveys to locate lesser prairie‐chicken leks in Texas and New Mexico using a Cessna 172 airplane (C172), R‐22 Beta II helicopter (R‐22), and R‐44 Raven II helicopter (R‐44) during spring 2007–2008. We determined lek activity during surveys with remote cameras placed on leks and cross‐referenced time on the photo frame to time on our Global Positioning System flight log. From remote cameras we found that 305 leks were available for detection during survey flights. We determined lek detectability was 32.7% (95% CI = 20.3–47.1%) in the C172, 72.3% (64.50–79.14%) in the R‐22, and 89.8% (82.0–95.0%) in the R‐44. We created 16 a priori logistic regression models incorporating aircraft platform, distance to lek, survey date, lek size, and lek type to explain lek detection from aerial surveys. Our top ranked model included platform, distance, and lek type (model weight; wi = 0.288). We had four competitive models and model averaged to draw inferences. Model averaging showed that detectability was generally greatest with the R‐44, followed by the R‐22, and lowest with the C172, with a slight deviation from this ranking at increased distances. Within our transect width, model averaging also suggested that detectability decreased as distance from the transect to the lek increased during helicopter surveys, and detectability increased as distance from the transect to the lek increased during C172 surveys. Furthermore, man‐made leks were more likely to be detected than natural leks and large leks were more likely to be detected than medium or small leks. Aerial surveys effectively locate new leks and monitor lek density, and alleviate weaknesses associated with ground‐based monitoring. We recommend using the R‐44 to conduct lek surveys while flying at an altitude of 15 m at a speed of 60 km/hr on sunny mornings. © 2011 The Wildlife Society.
