ESTONIA Pärnu county (Kergu + Kerli)

- they are often chirping - to me mostly it is the youngest chick (some times it is begging, but not every time)

AI answered:
- these sounds are for maintaining contact within the brood
- the youngest chick may be in a slightly different developmental phase, with more vocal practice (or stronger begging instincts)
- the chick may be stressed or trying to assert itself vocally in a nest with more dominant siblings
- some birds, even in the same brood, have individual differences in temperament and vocalization habits - the youngest may simply be more vocal by nature

EDIT:
KERGU feeds the chicks (dark head + the ring number), but again this unusually direction for him
slow-motion helps

again double feeding - first rain of fish, second regurgitating - maybe frogs

12.12.54 Kerli - FEEDING - 12.13.32 out (38 sec)

12.18.18 Kerli in again and she feeds the chicks - 12.18.54 out again (36 sec)

repeat - slow motion: Kergu regurgitated only this one piece of something (pellet?)
