Have you changed your own schedule, such as when you get up?
Maybe you can back them up, or move them forward, slowly.
For example, if you want them to move forward, set your alarm for 4, and go in and give them what you are now, but so that it's a solid 4. After a few days of that, move it to 4:30, the 5, etc.
We now give Sluggo one of those small wet food containers just before bed, and it seems to be working, but if we don't go to bed as planned, and watch something, she will act as though she didn't get it when we actually get ready for bed. I think that she suffers a little from age-related memory problems.
I don't know which part of Texas, but I saw a Lone Star show which said that at least part of Texas has a very healthy dove population. I guess that some of them have decided that you are a friendly human, and settled at your place!
I looked up Inca doves, and they are really interesting looking! Their chests have lines that look like tree bark, and the top of their wings probably also do, but kind of remind me of shingles.
ROTFL! Neighborhoods, eh? lolol!
The songbirds are tattletales! :-)
Good luck with getting Soli's days and nights back in order!
Love All Life, Thank You For Posting! :)
