Yājṣavalkya, the son of Devarāta, then vomited the mantras of the Yajur Veda and went away from there. The assembled disciples, looking greedily upon these yajur hymns, assumed the form of partridges and picked them all up. These divisions of the Yajur Veda therefore became known as the most beautiful Taittirīya-saṁhitā, the hymns collected by partridges [tittirāḥ].
Purport
According to Śrīla Śrīdhara Svāmī, it is improper for a brāhmaṇa to collect what has been vomited, and so the powerful brāhmaṇa disciples of Vaiśampāyana assumed the form of tittiras, partridges, and collected the valuable mantras.

Translation
Yājṣavalkya, the son of Devarāta, then vomited the mantras of the Yajur Veda and went away from there. The assembled disciples, looking greedily upon these hymns, assumed the form of partridges and picked them all up. These divisions of the Yajur Veda therefore became known as the most beautiful Taittirīya-saṁhitā, the hymns collected by partridges (tittirāḥ).
Yajṣavalkya was the son of Devarāta. Since it was improper for brāhmaṇas to take something which was vomited, they became partridges and received those verses. Therefore the saṁhitā is called Taittirīya, “coming from partridges.”
