Population Studies on Red Grouse, Lagopus lagopus scoticus (Lath.) in North-East Scotland

MATRILINEAL GENETIC STRUCTURE AND FEMALE-MEDIATED GENE FLOW IN RED GROUSE (LAGOPUS LAGOPUS SCOTICUS): AN ANALYSIS USING MITOCHONDRIAL DNA

“…Certainly, the very low levels of male dispersal are appropriate. Extreme natal philopatry coupled with territoriality does tend to prevent effective male dispersal (Jenkins et al 1963(Jenkins et al , 1964Hudson 1986). However, the extent of female dispersal has been less intensively studied.…”

Investigating the loss of recruitment potential in red grouse (Lagopus lagopus scoticus): the relative importance of hen mortality, food supply, tick infestation and louping-ill

“…Potential causes include weather, diet quality, predation, ticks and LIV (Jenkins et al 1963). The high levels of losses (between 70 and 90 %) compared with the 45 % losses were reported by Thirgood et al (2000a, b).…”

The first foreign recovery of a British-ringed bird and the first single-species ringing projects

“…In total, 13,336 birds were ringed with specially made rings, slightly smaller than the BTO's size 3, and bearing the address 'Aberdeen University'. Over 1,200 birds were subsequently recovered and the results were included by Jenkins et al (1963). Recoveries continued to be received for several further years, though a failure of collective and individual memory led to staff at Aberdeen University telling finders of rings discovered as late as 1991 that they had come from the Landsborough Thomson scheme.…”

“…Grouse are remarkably sedentary and this emerged almost at once from the first (Witherby) scheme. Grouse movements (or lack thereof) were described in more detail by Jenkins et al (1963), where mortality data were also presented. It is ironic that three of the first single-species ringing projects investigated a bird that goes nowhere.…”
