2.3 Insect Sampling and Home range delineation
To determine if GFWO were selecting nesting sites and home range sizes based on available insects, we compared home range sizes to the available insect biomass within each sample site. Home range size was estimated by constructing minimum convex polygons (MCPs) on a randomly chosen subset of the home ranges (n = 24). We constructed MCPs by recording male movements over four, 30-minute visits that began after observing a male leave their nest (Dudley & Saab, 2007). We recorded 120 observation points for each male and built MCPs using the minimum bounding geometry tool in ArcGIS version 10.3 (Environmental Systems Research Institute, Redlands, CA, USA)
Within the same subset of home ranges, along with the associated unoccupied sites, we quantified the availability of insects with an array of 11 sweep net sampling locations from the center of the site (0 m) outwards in 15 m increments to 150 m (see Figure S2), visiting each site once per week from May to mid-July 2019 (Doxon, Davis, & Fuhlendorf, 2011). We sorted the insects by order, dried them using an Elite Eliminator Heater set at 55°C, and weighed them every 24 hours until their mass stabilized.
