Baby pigeons stop being fed by their mother and start eating seeds

One of the best ways to try to get them to wean is to sprinkle the seed on the ground and not into a bowl. The roundness of the seed apparently kicks off the pecking instinct.

I've hand reared literally hundreds of pigeons over the years - as the bird gets to about four weeks old, I begin to cut the morning feed and leave them to peck around during the day as they get hungry -- it's really no different from their parents beginning to cut back on the feeding a bit as they get to about 34 days or so - I always give them a full evening feed.

How do racing pigeons choose a mate?

The strong survive tells all to your question, the Pigeon you see Strutting, head bobbing, charging type of behavior is the male, he is trying to woo a hen into submission, I am a Pigeon/Wildlife rescue & rehab person, I have many pigeons here, I have nesting boxes and watching the males try to lure a female into a nesting box is fun to watch, Males will also compete for a hen, some fights can become vicious.
The Pigeons do mate for life, however the (for life) issue can be looked at differently, If something was to happen to a Pigeons mate the survivor will except another mate in due time.
One is a lonely number.
They will only have 2 babies at a time, depending on the weather they will have up to 3 clutches per year.

ROC Racing Pigeons

Image by Atomische • Tom Giebel via FlickrThe Taiwanese very much enjoy racing Homing Pigeons over long distances. the military picked up on the idea, and made good use of it.

Could it be that China is afraid to fire those 1200 missiles pointed at the island of Taiwan because they know about the "Homing Pigeon" weaponry the ROC has? It's a signal sent at inbound missiles (yes, the ROC has the means to do that) which reprograms the missile's assigned target code and make it "return to base". Nifty trick.

We have here the queen of lies and CI has the gall to say something is not true!!!!! This has got to be a first!!!! The US is talking to Taiwan about a few old diesel electric subs and a dozen or so old F-16's, if Taiwan is so weak why are the PRC so pissed about this? All this stuff is old and I think the aircraft were only to be used to gather up the pigeons and bring them home if they got lost. The subs were only to save any pigeons that fell into the salt water.
