“…Thus, these individuals will most likely make use of one or more European stopover sites after departing Ottenby. We also report that fuel load increased as the season progressed in juveniles but not in adults, as described in Red Knots (Helseth et al 2005a, Meissner & Kamont 2005 and Common Sandpipers (Iwajomo & Hedenström 2011). Wichmann et al (2004) found strong evidence that juvenile Wood Sandpipers are more vulnerable to time and energy shortages during migration than are adults.…”

“…The difference in concentration of migratory direction is similar to findings of Holmgren & Pettersson (1998). Even considering the age-dependent difference in direction, both age groups mainly follow the Mediterranean Flyway, as suggested by Myhrberg (1961), rather than the East Atlantic Flyway used by most other wader species stopping over at Ottenby (eg Helseth et al 2005a(eg Helseth et al , 2005b; but see Hedenström 2004, Fransson et al 2008, Iwajomo & Hedenström 2011. In particular, the Camargue area (France) and northern Italy seem to be frequently used as stopover sites (Fig 2).…”

“…At Ottenby, many studies have focused on population trends, morphometrics and migration phenology of waders (eg Edelstam 1972, Mascher & Markström 1976, Holmgren et al 1993a, b, Waldenström & Lindström 2001, Blomqvist et al 2002, Hedenström 2004, Helseth et al 2005a, b, Iwajomo & Hedenström 2011. Furthermore, for Ruddy Turnstones Arenaria interpres (Helseth et al 2005b) and juvenile Common Sandpipers Actitis hypoleucos (Iwajomo & Hedenström 2011) population declines have been reported. At the continental level, Sanderson et al (2006), while analysing population trends in European breeding bird species, showed that the Wood Sandpiper declined in population within the period 1970 to 1990 but showed no significant change from 1990 to 2000.…”

Considering the decrease in numbers reported for similar wader species at Ottenby it is important to investigate population trends in wader species such as the Wood Sandpiper passing through Ottenby, especially using agerelated data that may reveal masked changes (Iwajomo & Hedenström 2011).…”

Long-term ringing data are useful for understanding population trends and migration strategies adopted by migratory bird species during migration. To investigate the patterns in demography, phenology of migration and stopover behaviour in Wood Sandpipers Tringa glareola trapped on autumn migration at Ottenby, southeast Sweden, in 1947 − 2011, we analysed 65 years of autumn ringing data to describe agespecific trends in annual trappings, morphometrics and phenology, as well as fuel deposition rates and stopover duration from recapture data. We also analysed the migratory direction of the species from recovery data. Over the years, trapping of both adults and juveniles has declined significantly. Median trapping dates were 10 July for adults and 6 August for juveniles. Average migration speed of juvenile birds was 58.1 km d −1. Adults stayed on average 3.5 days and juveniles 5.2 days, with average fuel deposition rates of 2.5 and 0.7 g day −1 respectively. Juvenile birds probably vary their strategy according to time of season and prevailing conditions. Both adults and juveniles followed the Mediterranean Flyway, but juveniles displayed significantly more southerly and significantly more scattered migratory directions.

“…Its autumn migration through Europe is well described according to the results of regular counts (e.g. Harengerd et al 1973;Winkler & Herzig-Straschil 1981;Meissner 1996;Mitrus et al 1998;Laber 2003;Iwajomo & Hedenström 2011) and analyses of ringing recoveries (Stiefel et al 1985;Meissner 1997;Cepák et al 2008;Fransson et al 2008;Saurola et al 2013). It is known that adult birds precede juveniles when moving towards the wintering grounds, but migration dates of both age classes overlap to a great extent (Meissner 1996;Balmori 2003).…”

In the common sandpiper both sexes do not participate equally in brood rearing. The attendance of females progressively declines and by the third week after hatching, most of them leave their broods. To check if this unequal parental care results in different migration phenology of males and females, adult common sandpipers were caught at four ringing sites in Poland during their autumn migration and were sexed using a discriminant equation. The median date of female migration was 6 days earlier than that of males. In the first days of July, males comprised only 22% of common sandpipers caught, while later their percent share increased gradually and in August reached up to 80% of captured birds. However, birds of both sexes were present among migrants during the whole migration period and migration period of both sexes overlapped to a great extent. Most probably birds migrating through the study area came from a vast breeding area, where the period of egg laying differs between its northernmost and southernmost parts by at least 1 month.

The number of breeding common sandpipers has declined in Britain due to poorer return rates from non‐breeding areas. To investigate little known aspects of their annual cycle, breeding common sandpipers were fitted with geolocators to track their migrations and determine their non‐breeding areas. Ten tagged birds left Scotland on 9 July (median dates and durations are given throughout the abstract). Short‐term staging was carried out by some birds in England and Ireland, then for longer by most birds in Iberia before continuing to West Africa, arriving on 28 July. Six birds spent most of the non‐breeding season (October–February) on the coast of Guinea‐Bissau, suggesting that this is a key area. Single birds occurred in Sierra Leone, Guinea, the Canary Islands and western Sahara. The southward migration from Scotland took 17.5 d (range 1.5–24 d), excluding the initial fuelling period. The first northward movement from Africa was on 12 April. Staging occurred in either Morocco, Iberia or France. Arrival in Scotland was on 2 May. The northward migration took 16 d (range 13.5–20.5 d). The main migration strategy involved short‐ and medium‐range flights, using tail‐winds in most cases. Variation in strategy was associated with departure date; birds that left later staged for shorter durations. Coastal West Africa provides two major habitats for common sandpipers: mudflats associated with mangroves and rice fields. Although the area of mangrove has been depleted, the scale of loss has probably been insufficient to account for the decline in sandpiper numbers. Rice fields are expanding, providing feeding areas for water‐birds. Meteorological data during the migrations suggest that the weather during the southward migration is unlikely to contribute to a population decline but strong cross‐winds or head‐winds during the northward migration to the breeding grounds may do so.
