Prior to tying the new transmitter, for each chicken are old (juvenile or mature), sexed and you may weighed

Growing specific administration recommendations, info will become necessary with the habitat alternatives and you will house variety sized turkeys at the its north assortment periphery. The first purpose in our research were to guess the brand new imply seasonal and you will annual family diversity size of ladies turkeys from the species’ north range boundary. We hypothesized one to household diversity size was top in the springtime while female seek a nesting site, therefore the minuscule from the wintertime and you can june. I and additionally hypothesized you to home range dimensions within species’ northern assortment was larger than the individuals stated regarding the southern area owed so you’re able to quicker restaurants availableness and habitat top quality. The next goal of our own analysis was to take a look at regular environment choices by women insane turkeys. I examined environment solutions from inside the good hierarchical manner, playing with Johnson’s (1980) second and you will 3rd sales out of possibilities throughout the each one of the four annual 12 months. We hypothesized you to habitat options manage change within season, that have turkeys mainly in search of deciduous and combined forest, but shopping for unlock habitat if you’re brood-rearing in the summer. Our latest purpose would be to evaluate if supplemental dinner influenced crazy turkey habitat selection. I hypothesized one to north wild turkeys need extra dinner about winter; ergo, i forecast one to girls will be discovered next to extra dining provide regarding bird feeders and you can livestock businesses in the fall and you will winter.

Data town

We learnt wild turkey ecology of for the Northern Bruce Peninsula, situated in Ontario, Canada (Fig. 1). Brand new Bruce Peninsula contains a variety of belongings protection products, into dominant protection becoming coniferous forest, mixed tree, fields, and you can deciduous tree (Dining table 1). Within rural neighborhood new principal marketplaces try farming and you will tourism. The main style of agriculture try small-level beef agriculture, and many tourist see during the summer due to a couple federal areas in the region.

Trapping and you may approaching wild turkeys

When you look at the wintertime, turkeys congregate for the large flocks, where you could trap multiple birds simultaneously. We caught up turkeys away from during the four places along side research town. Turkeys was baited having corn and you can captured using a skyrocket internet (Grubb 1988). Lure hemorrhoids was established in sphere alongside where turkeys was roosting. Just after turkeys were caught up, they were taken out of the net and put into import packets to have carrying. All the turkeys had been canned on location shortly after trapping. Whenever retrieving a poultry from its package, the base was indeed safeguarded and you will a great sock are put on their head. Animal care and attention acceptance are supplied by Trent University’s Creature Care and attention Panel (method zero. 22238).

We seized 53 turkeys, together with 47 women and you may half dozen people. We didn’t set transmitters towards the two lady on account of feather loss on their backs. I fit forty-five ladies turkeys which have sometimes an effective 73-g very high frequency (VHF) transmitter (model A1540 Advanced Telemetry Solutions, Isanti, Minnesota) or an 85-grams small gps system (GPS) sender (design G1H 261A Sirtrack, Havelock Northern, The fresh new Zealand). Thirty-seven of the women turkeys have been grownups and you may eight was basically juveniles.

Transmitters have been connected using a backpack style harness made of shock cord (Norman ainsi que al. 1997). The new mini GPS transmitters was in fact changed just before deployment of the tying neoprene for the underside of each device to stop chaffing (Guthrie ainsi que al. 2011). To get rid of water damage and mold i secure brand new vent which have a water-resistant silicone polymer sealant and a little remove away from plastic material recording (Guthrie et al. 2011). Both kind of transmitters considered less than advised maximum out of 3% of mature lady weight (Millsp). Having character purposes for every chicken was suitable with a numbered aluminium butt-end leg band. We in addition to took blood samples out-of per bird making several morphological specifications (amount of tarsus, side, beard and you will tail).
