Insect ectoparasites on wild birds in the Czech Republic during the pre-breeding period

Wild passerine birds (Passeriformes) from the northeastern part of the Czech Republic were examined for ectoparasites during the pre-breeding period in 2007. Two species of fleas of the genera Ceratophyllus and Dasypsyllus (Siphonaptera: Ceratophyllidae), and 23 species of chewing lice belonging to the genera Ricinus, Myrsidea, Menacanthus (Phthiraptera: Menoponidae), Brueelia, Penenirmus, and Philopterus (Phthiraptera: Philopteridae) were found on 108 birds of 16 species. Distribution of insect ectoparasites found on wild birds during pre-breeding was compared with previous data from the post-breeding period. There was no difference in total prevalence of chewing lice in prebreeding and post-breeding periods. Higher prevalence of fleas and slightly higher mean intensity of chewing lice were found on birds during the pre-breeding period. There was a significant difference in total prevalence but equal mean intensity of chewing lice on resident and migrating birds

Kites (Milvus spp.) wintering on Crete

The winter months are an important part of the year for raptors as survival throughout this period is critical for the succeeding year’s population recruitment. We reveal novel insights into the wintering of kites (Milvus spp.) on the Mediterranean island of Crete, Greece. We use a combination of 1) direct field observations, 2) online photograph searches and 3) analysis of satellite telemetry data from a tagged hybrid Red Kite × Black Kite (Milvus milvus × M. migrans migrans). The number of observations of wintering kites has increased since 1998. The wintering of numerous Black Kites with morphological features of both subspecies (M. migrans migrans and M. migrans lineatus) and a hybrid Red Kite × Black Kite is a new phenomenon on Crete.</p
