Abstract
Porodica čaplji (lat. Ardeidae) pripada redu rodarica (Ciconiiformes) za koje je karakteristično gniježđenje u kolonijama te uska povezanost s vodenim staništima. Cilj ovog rada je istraživanje dinamike i gniježđenja populacije kolonijalnih čaplji (Ardeidae) u Posebnom Ornitološkom rezervatu Krapje Đol u Parku prirode Lonjsko polje. Istraživanje je provedeno u svibnju i lipnju 2013. godine.Zabilježeno je pet vrsta čaplji: gak kvakavac Nycticorax nycticorax Linnaeus 1758, ţuta čaplja Ardeola ralloides Scopoli 1769, mala bijela čaplja Egretta garzetta Linnaeus 1766, čaplja danguba Ardea purpurea Linnaeus 1766 i siva čaplja Ardea cinerea Linnaeus 1758. Također,zabilježen je prvi pokušaj gniježđenja čaplje govedarice Bubulcus ibis Linnaeus 1758, te pojavljivanje blistavog ibisa Plegadis falcinellus Linnaeus 1766. Zabilježeni broj parova uspoređenje s podacima o gniježđenju od 1962. do 2012. Istraživani su i pravci odlaska na hranilišta te dnevna dinamika navedenih vrsta čaplji tijekom svibnja i lipnja. Utvrđena je znatno veća aktivnost u lipnju u odnosu na svibanj. Glavni smjerovi odlaska na hranilišta su sjever-sjeverozapad duž područja Lonjskog polja, te sjever-sjeveroistok u kojem se nalaze ribnjaci Lipovljani. Glavni utjecaj na broj gnijezdećih parova imaju intenzifikacija poljoprivrede, regulacija Save te promjene hidroloških uvjeta.

Parallel abstract (English)
Heron family (Ardeidae) belongs to stork order (Ciconiiformes) which is characterised by nesting in colonies and association with wet habitats. The aim of this study was to investigate dynamics and heron breeding population in Special Ornithology Reserve Krapje Đol, Natural Park Lonjsko polje.The study was conducted in May and June 2013. Five species was recorded: Black-crowned Night Heron, Squacco Heron, Little Egret, Purple Heron and Grey Heron. It was also recorded the first attempt of Cattle Egret nesting and the presence of Glossy Ibis. The results were compared with nesting data from 1962.-2012. Main directions of departures towards feeding areas and daily dynamics during May and June were also investigated. Activities in June were increased comparing the May.Main directions of departures towards feeding areas were north-northwest, along the area of Lonjsko polje, north-northeast where is the fishpond Lipovljani. Main impacts on breeding population are agricultural intensification, river Sava regulation and changes in hydrology conditions.
