The hypothesis of associating pseudoscorpions with bird nest types was tested on the basis of an analysis of 480 specimens. Eleven pseudoscorpion species were found in 171 nests of 28 different bird species collected in Slovakia, Austria and the Czech Republic. The frequent appearance of Cheiridium museorum, Dactylochelifer latreillii, Chernes hahnii, Dendrochernes cyrneus and Allochernes wideri was confirmed. High proportion and association of Pselaphochernes scorpioides in hoopoe hollow nests with decomposed substrate, D. cyrneus in the Eurasian tree sparrow nest boxes and A. wideri in the nests of the tawny owls, the European scops owls and the European roller was proved. In contrast, C. hahnii and D. latreillii were related to the nest fauna of blackbirds and song thrushes, C. museorum to the nests of white wagtails situated on the ground and on buildings and C. cancroides to the nests in synanthropic habitats. Until present, the occurrence of 22 pseudoscorpion species has been confirmed in the bird nests of Central Europe based on the obtained results and published resources. According to the association to bird nests these pseudoscorpions were classified as (1) nidixenous species — Chthonius fuscimanus, C. tetrachelatus, Mundochthonius styriacus, Neobisium carcinoides, N. crassifemoratum, N. inaequale, N. sylvaticum, Chernes cimicoides, C. similis, C. vicinus, Allochernes powelli, Lamprochernes chyzeri, L. nodosus and Larca lata; and (2) nidiphilous species — C. museorum, C. cancroides, A. wideri, D. cyrneus, D. latreillii, C. hahnii, D. panzeri and P. scorpioides.
