THE FIRST ATTACK: viewtopic.php?p=54378#p54378

the (second) attack starts
(more here: viewtopic.php?p=54382#p54382)



the first egg is destroyed by the invasive floater immediately after landing


and the second as well

[marika.solo]

At the beginning of the season, there were fights for the nest. An unwanted stork was seen nearby several times (we saw the storks in a defensive position). Yesterday, we saw a foreign stork on the camera as well.
Today, the visit of this intruder ended badly for the eggs of Zico and Natalio. In my opinion, the foreign stork destroyed / crushed both eggs in its bill. The damage did not happen during the fight on the nest.

It seems to me it is the same male stork from the beginning of this season.

9:29 AM @Vida-LI​​
Buenos días. 08:13:34 en mi opinión, el atacante es el macho que estuvo en el nido antes de que llegara Natalio. Se pueden ver los tres puntos blancos en su cuello.

At 08:13:34, in my opinion, the attacker is the male that was in the nest before Natalio arrived. You can see three white dots on his neck.

I am glad that Vida and I share the same opinion.

the morning

Zica on duty

- Zica repeatedly up - maintenance - incubating

still only 2 eggs

[marika.solo]

The FIRST ATTACK

[marika.solo]

the key moment - Zica is pushed out of the nest





the nest remains empty

[marika.solo]

.


it seems there is territorial fight maybe
(in the next frame I see 3 birds - but I am not sure if these are black storks)

who arrives?



Zica returned to the nest with wet feathers on her head and neck. She likely fell into the water after the intruder pushed her out of the nest. The nest is above a flooded mine. She shook her neck, but now her whole body is visibly shivering. It looks like a reaction to the shock and the cold water.
She pooped on the nest rim and slowly returned to her eggs - maintenance (after arrival she observed them only).

After the morning attack, Zica is leaning over the eggs and clattering her bill. Even if the intruder was not visible on camera, she clearly sensed danger. This bill-clattering is a typical defensive signal. Combined with her wet feathers and body shivering later, it shows she was under extreme stress and likely fighting to protect the nest. Or a displacement activity.

Btw. The bill as a resonator: If her whole body was shivering from the cold and shock, her jaws could have been hitting each other uncontrollably. This sounds like bill-clattering, but it is actually a mechanical result of the shivering.



- some maintenance
08.02:40 Zica very carefully settled slowly down

[marika.solo]

someone again approached the nest



SECOND attack


very hard for us to see that
again pushed out of the nest and (both) falling into the abyss
