I was browsing through the Czech-Latin dictionary Glossarius by Magister Bohemarius Bartholomaeus de Solencia dictus Claretus, which also lists an impressive collection of zoology terms, and I found some ornithology terms which are quite hard to find other dictionary records of:
- Mentibus altilia prius ipsa domestica signa.
- Altile krzidlatko, kacze tintarus, alta letatko,
- Letka volatile, noss rostrum, ten frendula hic koss,
- Kossinye pennatum, ceix cziss, zlutekque vitellum,
- Pes noha, penna pero, sit penniletum holopero.
- Aculeus zehadlo, trup assillus et alaque krzidlo;
- Ruffilus czrmak, milvus lunak, sit avis ptak;
The are words tintarus (duck), frendula (blackbird), ceix (siskin, looks like a cognate), and ruffilus (redstart), which seem to be quite uncommon. Actually, the only bird from this list that corresponds to its contemporary Latin name is milvus (kite). Some of these words resemble hapax legomena, which isn't actually that much unlikely in this text (there are some uncommon Czech words too in other parts).
So I wonder, where can I find more information about these words? Quick googling doesn't let me anywhere (aside from this text), and Wiktionary doesn't have contain any of these words.
