Abstract We determined reference levels of minerals, fatty acids, and fat-soluble micronutrients in eggs from wild Attwater's Tympanuchus cupido attwateri and two (Minnesota, Nebraska) greater prairie-chicken T. c. pinnatus populations for comparison with eggs produced by captive Attwater's prairie-chickens to help guide formulation and evaluation of captive diets. Levels of all minerals found in wild Attwater's prairie-chicken eggs were similar to those in at least one of the two greater prairie-chicken populations, but these levels frequently differed between the two greater prairie-chicken populations. Ratios for n-6:n-3 fatty acids were >3 times higher for Minnesota greater prairie-chickens, which had more access to waste grain than Attwater's or Nebraska greater prairie-chickens. Captive eggs had n-6:n-3 ratios 6.7 times the pooled wild samples, while wild eggs had higher levels of anhydrolutein, zeaxanthin, β-carotene, and total carotenoids. More magnesium, zinc, and manganese were observed in wild eggs compared with those produced in captivity. Flaxseed was added to the captive breeder diet in an attempt to lower egg n-6:n-3 ratios, along with additional carotenoids found in marigold extract. These dietary modifications successfully lowered the n-6:n-3 ratio by 46%, but this ratio was still 3.6 times higher in captive eggs, consistent with the grain-based formulation of the breeder diet. Carotenoid additions successfully raised total carotenoids, but increases were primarily for lutein and not zeaxanthin or β-carotene as intended. Variability in egg nutrient composition among the three wild populations suggests that some tolerance exists in maternal diets, but impacts to offspring fitness are unknown. Given the purported importance of maternal nutrition to fitness of embryos and neonate chicks, we suggest additional research is needed to quantify the influence of key nutrient levels on offspring fitness for both captive and wild populations.

Avian incubation involves behavioral decisions that must balance trade-offs between the incubating bird’s survival and current and future reproductive success. We evaluated variation in incubation off-bout duration and frequency among Greater Prairie-Chickens (Tympanuchus cupido pinnatus (Brewster, 1885)) in the Nebraska Sandhills, USA. Greater Prairie-Chicken life history favors incubation behaviors that prioritize success of the current breeding attempt over adult survival. Previous observations suggest incubating females make these behavioral decisions based on ambient temperature conditions, their own body condition, and predation risk. We monitored nest attendance by females at 30 Greater Prairie-Chicken nests to identify proximate cues used to make behavioral decisions regarding incubation. We recorded 930 incubation off-bouts. Females took 1.9 ± 0.7 off-bouts/day (mean ± SD), each with a mean (±SD) duration of 43.3 ± 24.1 min. Off-bouts were shorter in duration at higher wind speeds, at lower ambient temperatures, at nests with less cover, and at nests closer to roads. Females were most likely to leave the nest during mid-morning and evening, as are most gallinaceous birds, and incubation off-bouts became less frequent later in the season. We did not observe differences in incubation behavior between nests that failed and those that successfully hatched one or more chicks.
