Rufescent Tiger-Heron
26-11-16 © Jesús Fernández
In Rodo's photo of November 19th there is only one egg. In Jesus's there are two. The rufescent tiger-heron lays two to three eggs with a difference of days. It begins incubation right away as the egg is laid. Consequently, chicks hatch with that same difference. The older, bigger and stronger than its siblings, will monopolize food if it is scarce and will get rid of them if neccessary.
The hatching of eggs in a staggered way due to early incubation is known as asynchronous hatching. It is synchronous hatching when incubation begins when all eggs have been laid. This is the case of ducks. All hatch within some hours and they are all the same size.

This female shiny cowbird seemed pretty interested in the white-browed meadowlarks' movements. Knowing his parasitic behaviour it was no surprise. Anyway, a very low chance to be successful since the meadowlark passes by the reserve. There are no breeding records for this species

The cormorant has caught a a marbled swamp eel Synbranchus marmoratus and other cormorants chase it to steal it. This behaviour is known as kleptoparasitism and it very common among cormorants. The benefit for the "thief" is to avoid searching and hunting the prey. The cormorant tries to steal but it can not
