A total of 37 mite species was recovered from 11 of the 12 nests examined. The mite fauna was dominated by the family Macrochelidae. Macrocheles merdarius was the most abundant species, comprising 56% of all mites recovered. Most of the abundant mite species were associated with dung and coprophilous insects. It is likely that they were introduced into the nests by adult storks with dung as part of the nest material shortly before and after the hatching of the chicks.

In this paper we take the opportunity provided by a detailed monitoring scheme to examine several features of the timing and arrival pattern of White Storks (Ciconia ciconia) in Poznan  province, western Poland during the period 1983±2002. In doing so, we address several criticisms associated with the use of first arrival dates. We found no evidence of a weekend bias to phenological recording and, unlike in some other species, found no effect of population size on recorded arrival date. Some aspects of the arrival pattern got earlier over time and first arrival appears to have been about 10 days earlier in the last 20 years than in the previous century. Earlier arrival was associated with warmer spring weather and with a protracted arrival period. From our experience with this study, we suggest how the general public can be used to collect high quality phenological data.

Bird blood was tested for T. gondii antibodies by an indirect fluorescent antibody test. T. gondii antibodies were detected from 5.8% of 205 analysed white stork chicks and 13.6% of 44 analysed adult storks in the zoo. Because toxoplasmosis is one of the more common parasitic zoonoses worldwide, we briefly discuss the potential epidemiological importance of stork toxoplasmosis to humans.

Listeria antibodies were detected in 121 (59%) of 205 chick samples. The probability of Listeria antibodies being present increased with chick age; chicks detected with Listeria antibodies were in better condition than those without the bacterium.
