I'll keep you up-to-date :)
This morning around 9 am they were singing the call of mating.
What I don't understand is how they can look for mating with 2°c of temperature and they are looking for it every day with these temperatures.
Another example that I filmed 1/12/2019 5°c cloudy/rainy:
It seems that the collared dove that I filmed when it felt observed has stopped ... LooooooooL :)
In the south of Portugal there are on average 16 ° degrees today I think it is normal that the collared doves try to mate.
It's the first year that they do so here near 0°c ... it's a mystery :) :) :)
