סימן צח סעיף יד

יוֹנֵי שׁוֹבָךְ וְיוֹנֵי עֲלִיָּה, אַף עַל פִּי שֶׁכְּבָר הֻרְגְּלוּ לָבֹא לְקִנֵּיהֶן, אָסוּר לְצוּדָן, אֲפִלּוּ הִזְמִינָן מֵעֶרֶב יוֹם טוֹב.

It is forbidden to catch doves of a dove-cote or doves living in an attic,⁴⁸Wild birds that do not belong to anyone. even though they are accustomed to return to their nests⁴⁹Because they are not domesticated, they are hard to catch and are not considered as though they are already caught. Even if they are easy to catch, you may not catch them. Since they find their food elsewhere, they are like other wild fowl. (Magein Avraham. (see Mishnah Berurah 497:28) and even if you selected them before Yom Tov.⁵⁰If they are small and not able to fly and escape, it is sufficient to designate the ones you want before Yom Tov. (see Shulchan Aruch 497:9–10)

תנא דבי אליהו כל השונה הלכות בכל יום מובטח לו שהוא בן העולם הבא שנאמר הליכות עולם לו אל תקרי הליכות אלא הלכות (נדה ע"ג.)
