We hypothesized that home assortment size might be better regarding spring whenever you are female seek a nesting site, as well as the smallest throughout the winter season and june. We as well as hypothesized you to household range dimensions at species' northern range might be larger than those people stated in the southern area due in order to less dining access and habitat quality. Next goal of one's studies would be to examine seasonal environment choice by females nuts turkeys. We reviewed habitat choices in a great hierarchical trends, using Johnson's (1980) second and you may third purchases from possibilities throughout each one of the four yearly season. We hypothesized one to habitat alternatives create transform amongst the seasons, with turkeys primarily looking deciduous and you may blended woods, but trying to find discover habitat if you find yourself brood-rearing during the try here summer. Our finally mission would be to assess if or not extra dinner swayed wild chicken environment choices. I hypothesized that north insane turkeys need supplemental food on the winter; thus, i predict you to people was discover alongside supplemental restaurants provide from bird feeders and you will animals procedures regarding the fall and you will winter season.

I learned wild poultry ecology away from on the North Bruce Peninsula, situated in Ontario, Canada (Fig. 1). New Bruce Peninsula includes a combination of home safety sizes, into prominent security becoming coniferous tree, mixed tree, industries, and you will deciduous forest (Dining table step one). In this outlying people this new dominating marketplaces was farming and you will tourist. An element of the style of farming is quick-measure beef farming, and several tourist visit in the summertime because of a couple of federal parks in your neighborhood.

Trapping and approaching nuts turkeys

From inside the winter season, turkeys congregate from inside the high flocks, enabling you to trap multiple wild birds at a time. I swept up turkeys from at the four locations across the investigation town. Turkeys had been baited having corn and you will grabbed using a rocket net (Grubb 1988). Lure stacks was established in areas near to where turkeys was basically roosting. Just after turkeys was in fact trapped, they were taken out of the internet and put into import packages to possess carrying. Most of the turkeys was basically processed on location shortly after capturing. Whenever retrieving a chicken from its field, their base have been secured and you may an effective sock are apply the head.

We seized 53 turkeys, also 47 girls and you can half a dozen people. We didn't put transmitters for the a couple of lady due to feather losings to their backs. I complement forty five lady turkeys having sometimes a beneficial 73-grams very high frequency (VHF) sender (model A1540 Advanced Telemetry Possibilities, Isanti, Minnesota) or an enthusiastic 85-grams small global positioning system (GPS) transmitter (design G1H 261A Sirtrack, Havelock Northern, The newest Zealand). Thirty seven of your own people turkeys was indeed people and you will seven was indeed juveniles.

Transmitters had been affixed playing with a back pack style harness created from shock wire (Norman ainsi que al. 1997). The new small GPS transmitters had been modified ahead of deployment by attaching neoprene towards bottom part each and every unit to quit chaffing (Guthrie et al. 2011). To eliminate water damage i secured the vent with a water-resistant silicone sealant and you may a small strip away from plastic recording (Guthrie mais aussi al. 2011). One another particular transmitters weighed less than advised limitation out-of 3% from adult ladies weight (Millsp). Getting character intentions each chicken is actually fitting that have a designated aluminium butt-end leg ring. I in addition to grabbed blood products out of for every bird making numerous morphological proportions (amount of tarsus, wing, beard and tail).
