I hope the Natalio doesn't defend the nest from its chick (Dr.DA commented last year that if they don't see a begging chick for a few days, the instinct to feed quickly disappears; today I read that several factors contribute to this)
... Tajete seemed rather weak when left the nest ...
- to me it was again clearly defending behaviour:
1/ calling fanned tail feathers
2/ bill pointing upwards
3/ moving some nest material
3/ sitting down
