Uspješnost gniježđenja crne rode na području Parka prirode Lonjsko polje u 2014. godini

Abstract

Istraživanje uspješnosti gniježđenja populacije crne rode na području Parka prirode Lonjsko polje obavljena su u razdoblju od svibnja do srpnja 2014. godine prema Nacionalnom programu monitoringa gnijezdeće populacije crne rode. U tom razdoblju izvršene su dvije posjete gnijezdima crne rode na 14 lokacija koja su ranijih godina pronašli djelatnici Javne ustanove Park prirode Lonjsko polje i njegovi stanovnici. Utvrđeno je postojanje 10 gnijezda od kojih je 6 uspješno, odnosno u njima ima mladih. Samo je jedno gnijezdo bilo nepoznato, odnosno nije se moglo utvrditi ima li u gnijezdu mladih. Ukupno je evidentirano 16 ptića, od čega je u 2 gnijezda izbrojano po 2 ptića, a u 4 gnijezda je izbrojano po 3 ptića. Prosječni broj ptića po gnijezdećim parovima iznosi 2.28, a prosječni broj ptića po uspješnom paru iznosi 2.67 što predstavlja odličan uspjeh gniježđenja.Exploration of black stork breeding populations success int he area of Lonjsko polje – Nature Park were conducted in the period from May to July 2014 under the National Programme of black stork nesting monitoring. In this period were made two visits to nests of black storks at 14 locations that were found in previous years by the employees of Lonjsko polje - Nature Park Public Institution and Park inhabitants. Study revealed the existence of 10 nests of which 6 are successful, which means they contain young birds. Only one nest was unknown, which means it could not be determined whether the nest containing young birds or not. There were a total of 16 young birds, of which 2 nests were counted by 2 birds, and 4 nests were counted by 3 birds. The average number of chicks per nesting pairs was 2.28, and the average number of chicks per successful pair is 2.67, which is an excellent breeding success
