Zevachim7: 2
עוֹלַת הָעוֹף שֶׁעֲשָׂאָהּ לְמַעְלָה, כְּמַעֲשֵׂה עוֹלָה, לְשֵׁם עוֹלָה, כְּשֵׁרָה. כְּמַעֲשֵׂה עוֹלָה לְשֵׁם חַטָּאת, כְּשֵׁרָה, וּבִלְבַד שֶׁלֹּא עָלְתָה לַבְּעָלִים. כְּמַעֲשֵׂה חַטָּאת לְשֵׁם עוֹלָה, כְּמַעֲשֵׂה חַטָּאת לְשֵׁם חַטָּאת, פְּסוּלָה. עֲשָׂאָהּ לְמַטָּה כְּמַעֲשֵׂה כֻלָּן, פְּסוּלָה.
A bird olah which one made above, in the manner of an olah-offering, for the designation of olah, is valid. [If he made it] in the manner of an olah-offering for the designation of chatas, it is valid; but it is not credited to the owner. In the manner of a chatas-offering for the designation of olah, [or] in the manner of a chatas-offering for the designation of chatas, it is invalid. [If] he made it below in any of these manners, it is invalid.
Zevachim7: 3
וְכֻלָּן אֵינָן מְטַמְּאוֹת בְּבֵית הַבְּלִיעָה; וּמוֹעֲלִין בָּהֶן, חוּץ מֵחַטַּאת הָעוֹף שֶׁעֲשָׂאָהּ לְמַטָּה, כְּמַעֲשֵׂה חַטָּאת לְשֵׁם חַטָּאת.
And all of them do not contaminate with tumah via the throat; but one is subject to the laws of me’ilah on their account, except for the bird chatas which was made below in the manner of a chatas offering for the designation of chatas.
