palmetto corn snake

2017. gada marta sākumā tika secināts, ka ziemā melno stārķu ligzdas kokam nolūzis liels zars, kas krītot ir nolauzis vienu no ligzdu balstošajiem zariem, turklāt palicis iekāries ligzdā. 5. martā ornitologi ar profesionāla arborista Rolanda Kāpostiņa palīdzību veica koka apsekošanu un zars tika nozāģēts, lai melnie stārķi, atgriežoties no ziemošanas vietām, varētu arī šajā sezonā uzsākt veiksmīgu ligzdošanu.

The Great bittern (Botaurus stellaris) nest in Latvia is located in the vast reedbeds of Lake Engure. The nest was found on April 24th, 2015 with three eggs in it and a couple days later one more egg was laid.

The species has only one brood a year, 3-7 eggs are laid in April-May and the hatching time is 25to 26 days. The female is the only one to feed the young. The species starts incubating after the first egg is laid, thus the chicken’s age in one nest can differ by 2-3 days.

These live cameras operating season will be shorter than we are accustomed to when observing the lifestyle of birds of prey. This is because after hatching, the chicks spend about two weeks in the nest and then disperse amongst the reeds.
