Today among several breeding records I obtained, are these two that raise very similar questions. Both nests were about 2 metres above ground.

 

1 -  On McQuoids Hill: A pair of Striated Thornbills moving around a tree with beak full of insects going towards a dense patch of leaves, that patch on examination contained a typical thornbill nest and buzzing sounds heard as adults entered nest and came out without beak full of insects. I don’t recall having seen a Striated Thornbill nest before.

 

2 -  On Mt Taylor: A pair of Weebills moving around a tree with beak full of insects going towards a dense patch of leaves, that patch on examination contained a typical weebill nest (I have seen several) and adults appeared to want to go to the nest but wouldn’t go in whilst I was close enough to observe (about 2 metres away). This one on Mt Taylor would be easy to find again.

 

What I really have is a CF but that is not very useful to indicate an actual nest found, or an ON, although I think I can do better than that. I recorded both as NY as that appears logical, even though I didn’t see chicks in either and I infer them at hearing sounds at one. Of course if one adult feeds another at a nest that would be wrong. But I don’t think they do.
