Daf Yomi - Beitza 10 - Dove Brooding

Rashi explains that the first brood of the season is kept as company for the mother. The first brood is generally born in the month of Nissan. They usually have two offspring, one male and one famale every month except during the winter.

Rashbam in Bava Basra (80a) states that they have offspring every month of the year except for the month of Adar.

Sheorim Mitzuyanim B'halacha suggests that it might depend on the climate of each particular area.

Below is a picture from the first brood; the parent is on the right and the nearly-grown fledgling is on the left.

nice post!
I take off on what you write here on my own blog (parshablog) here,
where I cite you, not the dispute between Rashi and Rashbam.

I try to bring the ancient and modern science to bear on this topic.

Kol Tuv,
