How the meek will be inheriting the Earth...

My partner and I have been looking after mostly domestic doves , also occasional wild doves who cannot be released, such as our Herkimer who is an American Common Ground Dove, and a tiny fellow, the size of a grown sparrow.
These doves teach us many lessons, every day. Even though they have no other defense except to be able to fly away (their beaks are soft, if you touch a young doves' beak, you feel soft, warm skin! They certainly don't have scary claws on their feet, for they're just enough to cling to a branch with, and even on the grown, older doves, when they trust you enough to roost on your hand, you can feel the skin on their feet is also soft and warm. And when you lift Mom or Dad dove to check their chicks, they bat and slap at you with their wings, but even on the largest ones ((the pigeons)), they simply don't generate enough force to hurt anyone, not even one another)...so how would they continue to survive when the bigger meaner critters (us human killers, the meanest over-all) go to kill all of them as well as one another?
Simple, they out-parent us.
Even the worst doves make better, more attentive parents than the smartest humans.
When eggs are made, each parent dove takes turns incubating it. If anything happens to one of the parent birds so that only the other is left, and the weather is too cold to safely be away off the nest, then the remaining parent will stay on those eggs until they hatch, even if it takes the whole 21 days, and stay close to the hatched chicks for the critical initial first five days after hatching until they at least have their own insulating feathers.
If both parent birds are able to stay involved with their chicks, then the father-bird will also take turns providing doves' "milk" for the babies, who push their skin-soft beaks down into their parents' crops to get this mashed seed plus a kind of milk that each parent bird will produce for their chicks. They will do this for about three weeks until their young fledgelings are well able to fly and get around on their own.
They will also raise chicks in any weather, and all year around. We have seen several successful pairs of breeding doves raise as many os 8 sets of chicks or more in a single year, this way.
Doves are known as seed-eaters, but did you know they will also take on insects, small worms and small grubs?
With the careful attention that each parent gives and their complete willingness to sacrifice anything for their young, even their very lives if that's what it takes, it's no wonder to me that the "meek" shall inherit the Earth.
They seem to have a tendency to out-parent us and most other species as an unbeatable survival technique.
