I would first like to extend my deepest condolences regarding the loss of your canary. I have had MANY friends throughout my life that have accidentally left the cage door open. NONE of them EVER came back. Perhaps, yours will be different. I suppose we can hope for the best. The ONLY way to attract your canary is to have fostered a relationship in which it would not want to leave in the first place. For all we know, it has found it's natural home already. Chin up, and good luck.
Canaries do knock eggs out of their nest. This is done sometimes if the bird knows the egg is not thriving. Eggs may be knocked out of nest by predators to the canary bird also.
because canary's are not wild birds. they usually live in cages in people's homes.
yes it make a nest. they make a nest like an ant.
dolphins do not make nest
They make the nest out of pebbles or rocks that they find.
You can't really build a nest the birds way, but you could make a giant nest for a person, which would probably be easier to make. I once made something like that. But if you were to build a nest, you'd have to know which type. Different birds build different looking nests. Let's say you're some generic type bird or whatnot and are nesting in a tree. You would have to attach your nest to the earth somehow. You'd either put mud on it or something like that or attach the sticks to it. Next come the actual building of the nest. You'd have to intertwine sticks and hay and grass and things like that to get a bowl shape or whatever shape you desire. If you were a bird, you'd put in some of your breast feathers and such to make the nest warm and cozy for your chicks. Building a nest is harder than it sounds and I advise you leave it to the professionals.
where dose the sarus crane make its nest
owl nest
This may have been an accident. The bird may have laid too many eggs to fit in the nest. Discard the fallen egg and all should go fine.
Hopefully, sometimes first time does will not make a nest and sometimes they will make a nest but not have babies (psuedo pregnancy).
it is the male and female that make the nest. if there is only a male then it may be harder to build a bigger nest.
