Do any other birds lay eggs w/o being fertilized first?

My cockatiel lays infertile eggs from time to time. I'm sure all birds do it depending on circumstance.

Ohhhhh...LOL. I get your point now
So you're asking if any other BIRDS (only) will lay whether the egg's been fert. or not. Sorry - first cup of coffee. Hmmm...ducks? geese? Dang - now you've got me curious...

So far as I know, all birds will lay eggs whether fertilized or not...the type of bird dictates the amount of eggs...

Then that brings up another question....why lay eggs if not fertile? I realize nature is extremely wasteful when it comes to reproduction, but usually in the other direction......way more fertility to make sure a few make it too maturity. What's the rationale in non-fertile egg laying?​

I don't think all birds will just lay. For example, the kiwi lays one egg but it is close to weighing one pound. That's a lot of energy expenditure. Generally, female birds that have the most energy expenditure lay the least amount of eggs while birds with small eggs and less time investment lay more often. Time investment meaning that they are the primary caregivers. Other species where the males are the primary caregivers, the females mate more and lays more with varying males in order to diversify the gene pool.

...because in the wild they have 1,000% more chance of access to a male?

I'm sure their hormones initiate egg production - only semi-dependent on the presence of a male.

I have, in the past, raised Bobwhite quail, zebra finch, society finch, cockatiel, and I have raised parakeets. They all will occasionally lay eggs even without the male. I believe chickens were domesticated due to the frequency of laying and the size of the eggs. Have you ever seen a finch egg? Take and awful lot to make an omelet!
