Rashi on Leviticus 11:19/רש"י על ויקרא י״א:י״ט

1החסידה — This is the white stork, cigogne in old French And why is it called חסידה? Because it deals kindly (חסד) with its fellows in respect to food (Chullin 63a).

2האנפה — This is the hot-tempered דיה, and it seems to me that it is what is called heron.

3הדוכיפת — the wild cock which has a double comb (כרבלת). In O. F., herupé; (English = hoopoe). And why is its name called דוכיפת? Because its ornament (הודו) is tied tegether (כפות): this refers to its comb (which being doubled, appears to be tied up). It is also called נגר טורא, mountain-splitter, because of its doings, just as our Rabbis explained in Tractate Gittin 68b in the chapter commencing שאחזו ‎‎מי.
