Falconry
In the seventies, I was breeding peregrines by the basket, but I tried, without success, to breed gyrfalcons for more than 13 years. After that, I was convinced that it could not be done and was happy just to keep some alive. The Lord must have felt sorry for me, because finally in 1982, without doing anything different, one pair of gyrs courted and laid eggs.
During the breeding season, we come quite often against this situation where we have to take one or all eggs away from a parent....
More than thirty years ago, when I bred the first Tundra peregrine falcons, I accidentally cracked and damaged one egg. I fixed the egg with clear silicone and kept putting it back in the old “Marsch Farm” incubator, turning and cooling it by hand....
