“…Our survival rates of chicks (Fig. 2) were marginally higher than the 19% (six of 31) of radiotagged chicks that survived in the north Pennines (Whittingham et al 1999), where predation by Stoats was the main cause of mortality (Whittingham et al 2002). Broods hatching at the end of May or beginning of June appeared to have the greatest chance of survival (Fig.…”

“…Although relatively high levels of predation can occur on some grouse moors (Whittingham 1996, Whittingham et al 1999, the low level of nest and chick predation at Snake Summit support the hypothesis that grouse moor management can enhance Golden Plover breeding success, and may explain the association between Golden Plovers and grouse moors (Tharme et al 2001). Experimental work to examine the effects of temporal changes in predator control upon Golden Plover breeding success is required to confirm this (cf.…”

“…n is the total number of intervals (B2 days in godwits, B3 days in lapwings) for each type siblings, as in the godwits, but a study in the UK did observe that poor condition induced by repeated handling reduced the survival of lapwing chicks (F. Sharpe et al, unpublished). Other studies have generally not found adverse effects of back-or leg-mounted tags in chicks of shorebirds and gamebirds (Kenward et al 1993;Whittingham et al 1999;Grant 2002). Nevertheless, there may be effects of telemetry studies that cannot be detected by within-brood comparisons.…”

“…A potential drawback of radio-tagging is that the transmitters may affect the chicks' behaviour or physiology and reduce their survival prospects. Thus, it is important to check whether such negative effects influence the outcome of telemetry studies (Kenward et al 1993;Whittingham et al 1999;Grant 2002;Krapu et al 2006).…”

Grassland-breeding shorebirds show widespread declines due to a reduction in breeding productivity following agricultural intensification. However, there is also concern that increasing predation causes further declines or precludes population recovery. Predation may itself be enhanced by agriculture through changes in habitat or food availability, but little is known about the mortality of nidifugous shorebird chicks. We studied mortality by radio-tagging 662 chicks of Black-tailed Godwit Limosa limosa and Northern Lapwing Vanellus vanellus in 15 farmland sites in the Netherlands. Tagging and handling had no effect on the condition and survival of godwit chicks, but body condition was reduced by 6-11% in lapwing chicks wearing a tag for longer than 3 days. Fledging success was 0-24% in both species. Mortality was highest in young chicks but remained considerable until after fledging. Losses were traced mostly to predators (70-85%; 15 species, predominantly birds), but at least 5-10% were due to mowing, and 10-20% were due to other causes, including entrapment in ditches and starvation. Chicks staying in fields that were cut before the next radio check were found much more often as mowing victims and somewhat more often as prey remains than chicks in fields not cut, indicating that predation includes a limited amount of scavenging. The predation hazard for godwit chicks was higher in recently cut or grazed fields than in the tall, uncut grasslands they preferred, while that for lapwing chicks was lowest in grazed fields. In godwit chicks, poor body condition increased mortality risk, not only from starvation but also from other causes. Predation on godwit chicks was thus enhanced by intensive farming through a decline in the availability of cover, augmented by a reduced body condition, possibly due to food availability problems. Changes in farming practice may therefore help reduce predation pressure, though the observed interactions explained only part of the high predation rate in godwits and none in lapwings. Predator abundance has increased in Dutch wet grassland regions, and chick predation has become a factor that should be considered in planning the type and location of conservation measures.

“…The transmitter is attached to the bird with glue. Various types of glue have been used, including cyanoacrylate glue, bird epoxy (obtained from Eclectic Products Inc., 4507 Willametter Blvd, Pineville, LA 71360 USA) and Saltair Ostemy Adhesive Solution (Whittingham et al 1999). Depending on the age of the bird, and timing of molt, transmitters glued to the back will remain on the bird for a few days to months.…”
