Marta Witkowska, Auteur ; Wlodzimierz Meissner, AuteurThe Curlew Sandpiper (Calidris ferruginea) displays sexual dimorphism in size and in breeding plumage. We analysed biometric and plumage characteristics in adult Curlew Sandpipers and proposed a protocol for sexing individuals, with the use of t[...]

Wlodzimierz Meissner, Auteur ; Grzegorz Zaniewicz, Auteur ; Patrycja Gogga, Auteur ; Lucyna Pilack, Auteur ; Marcel Klaassen, Auteur ; Clive Minton, AuteurStudies of moult of flight feathers have traditionally used the moult score, in which primaries were scored between 0 (old) and 5 (fully grown new primary) and added up. The moult score eventually became increasingly replaced by the percentage o[...]

Grzegorz Zaniewicz, Auteur ; Wlodzimierz Meissner, Auteur ; Agnieszka Ożarowska, AuteurFat is the main source of energy during bird migration, and the visual fat scoring is widely used in the studies on, e.g., stopover ecology of migratory species. Yet, visual fat scoring can lead to wrong conclusion due to potentially different p[...]

Piotr Minias, Auteur ; Wlodzimierz Meissner, Auteur ; Radoslaw Wlodarczyk, Auteur ; Agnieszka Ożarowska, Auteur ; Anna Piasecka, Auteur ; Krzysztof Kaczmarek, Auteur ; Tomasz Janiszewski, AuteurMigration is an energetically expensive and hazardous stage of the annual cycle of non-resident avian species, and requires certain morphological adaptations. Wing shape is one of the morphological traits that is expected to be evolutionarily sh[...]
Article
Wlodzimierz Meissner, AuteurRedshanks were counted daily at three sites at the Gulf of Gdansk. The dynamics of migration differed between studied seasons. However, in the majority of years the pattern showed a clear wave structure. It is known that two different population[...]

Article
Wlodzimierz Meissner, AuteurBiometrics of the Redshank migrating in autumn through the Gulf of Gdansk were studied between 1983 and 1990. A total of 78 adult Redshanks and 775 juveniles was caught and measured. On average all measurements of adults were longer than those o[...]
Article
Different scoring systems have been developed for assessing fat stores in birds. Most have been used with passerines, and there is no widely used standard for studies of shorebirds. I developed a new fat-scoring classification scheme for shorebi[...]

Article
Natalia Karlionova, Auteur ; Wlodzimierz Meissner, Auteur ; PAVEL Pinchuk, AuteurWe studied the development of breeding plumage in 641 Ruff Philomachus pugnax males during spring in 2004-2006 in southern Belarus with special emphasis on the growth rate of ruff and tuft feathers, which are the most colourful and spectacular p[...]

Jacintha G. B. van Dijk, Auteur ; Wlodzimierz Meissner, Auteur ; Marcel Klaassen, AuteurHydrogen stable isotopes (H-2) in feathers are used to determine the origin and migration strategy of birds. To identify the geographic location of the site of feather synthesis, calibration curves for the relation between feather H-2 and amount[...]
Article
Wlodzimierz Meissner, Auteur ; Magdalena Remisiewicz, Auteur ; Lucyna Pilacka, AuteurCharadrius plovers generally show little sexual or seasonal dimorphism in size and coloration, but most published measurements come from museum specimens. We aimed to determine sexual size dimorphism in live Kittlitz's Plovers Charadrius pecuari[...]
Article
Wlodzimierz Meissner, AuteurThis long-term study (10 years) aimed to check if the sex-ratio of dunlins Calidris alpina at a stopover site in the southern Baltic region was biased. Two age classes among non-juvenile dunlins were recognised: immatures (2nd calendar year) and[...]

Reuven Yosef, Auteur ; Wlodzimierz Meissner, AuteurThis study was undertaken to understand the migratory strategies of the Dunlins (Calidris alpina) caught in Eilat, Israel, before and after they accomplish the crossing of the combined ecological barrier of the Sinai, Sahara and Sahel deserts. B[...]
Article
Wlodzimierz Meissner, Auteur ; Magdalena Remisiewicz, Auteur ; Patrycja Gogga, AuteurWe investigated the effects of sex and age on the progression of breeding plumage moult in the Wood Sandpiper, a migrant wader that shows weak sexual size dimorphism and no dichromatism. We sexed the birds by DNA and examined the plumage of 416 [...]

Sex identification of adult Dunlins Calidris alpina alpina migrating in autumn through Baltic region
Wlodzimierz Meissner, Auteur ; Lucyna Pilacka, AuteurEighty Dunlins Calidris alpina were trapped and measured in autumn in northern Poland and sexed by dissection or DNA analysis. A discriminant function, based on bill and wing length, was also constructed to predict the sex of adult Dunlins. This[...]

Wlodzimierz Meissner, AuteurFor Red Knots Calidris c. canutus sandy coasts of the southern Baltic seem to be a low quality stopover site, because of unpredictable feeding conditions and a low density of molluscs. Observation collected in the Puck Bay, Poland, suggest that [...]

Yahkat Barshep, Auteur ; Wlodzimierz Meissner, Auteur ; Les G. Underhill, AuteurRecent shifts in the timing of migration and breeding have been attributed to climate variation in some migratory birds. However, the divergent patterns in the timing of autumn migration among different bird species suggest a significant role of[...]
