Martha/all,

I -tried- ... unsuccessfully ... to make my question not about the
human constructs of time (hours, days, etc.) but rather to be about
the generic concept of - and awareness of - time. I don't expect
birds to be aware of Monday, the 23rd of May, 2022 ... I'm asking if
birds have any concept of time such as today/tomorrow/yesterday or
this morning/afternoon/evening. Broad concepts like that - not the
human constructs that divide time up into 'artificial' segments.

===> And wondering if anyone has seen any research on this topic.
If birds do understand time - it would, to me at least,
contribute to their 'intelligence'.
