In preparation:

  1. The results from Białowieża Forest.

    As a continuation of the Białowieża project done by the successors (Prof. T. Wesołowski and his team) the previous results have being published. In this framework the following studies are being prepared:
    1. Rates of reproduction and mortality in the Białowieża population of hawfinch C. coccothraustes. Part II.
      It is a model example of the species nesting high in the trees and subjected to very strong pressure of nest predation.
    2. Location of arboreal bird nests dependent on the cardinal directions, investigated in a primeval forest.
      For example, the relationship between the nest locations of song-thrushes and hawfinches, and factors such as temperature, insolation and predators was revealed.
    3. Breeding ecology in the primary population of song-thrush Turdus philomelos (2 papers). The distribution and the density as well as the rates of reproduction and mortality of the population have been analysed. The aim is to compare these rates from the primeval forest with the results previously obtained in the secondary environments (parks of some European cities). This will allow to distinguish between primary and secondary behaviour of this model species.

  2. Studies on bird assemblages nesting in urban habitats.

    Both doctoral and postdoctoral dissertations (from 1960s and early 1970s) on the composition and functioning of the bird assemblages or urban populations together with currently repeated investigations bring new knowledge: it reveals trends of the long-term dynamics in the avifauna of urban areas.
    1. In 2005-07, the first such comparisons were published, revealing the enormous variability of the composition and abundance of birds in urban parks. In 2007 and 2008 census of birds in the same areas in Wrocław were continued. Then two publications will be prepared: the first revealing trends of changes in avifauna of urban areas in Wrocław, and the second – a synthetic study with interpretation of opposite avifauna changes in Legnica and Wrocław, though occurring at the same time. The main factor responsible for this seems to be the oppositely oriented predator pressure, the factor underestimated in most bird ecology studies.
    2. Observations of the urban population of pigeon (Columba palumbus) have been continued including a period of over 40 years.

  3. Changes of condition in corvids Corvidae in western Poland.

    Since 2005 changes in the number of corvids in the agricultural landscape have been recorded in western Poland. The results obtained indicate a very strong decrease in the number of crows, rooks, jackdaws and partly magpies (with the expansion and the great number of raven populations), species which were increasing in numbers in the previous decades. Causes of these drastic changes have been investigated.

  4. Comparison of two models of area conservations: in Western and Eastern Europe.

    During the studies of European literature and trips abroad, considerable differences in the development of practical conservation of natural ecosystems have been noticed. The purpose of the study will be to convince administrators that both models should be used parallelly, and not regarded as competitive. Each of them has certain advantages, and each may be too one-sided.
