Cuckoo
The bird filed under "cuckoo" in older topical indexes is rendered "seamew" (or "sea-mew") in the UPDV. Both occurrences sit inside the dietary lists of forbidden birds — once in Leviticus, once in Deuteronomy — and in each the bird is named in a tight cluster with three others.
In the Leviticus List
The Leviticus list places the bird among ostrich, nighthawk, and hawk: "and the ostrich, and the nighthawk, and the seamew, and the hawk after its kind," (Lev 11:16). The verse itself is one line in a longer catalog of birds that "you⁺ will hold in abomination" earlier in the chapter; here the seamew is named as one of those four.
In the Deuteronomy List
The Deuteronomy parallel keeps the same four names and the same order, with a small spelling variation: "and the ostrich, and the nighthawk, and the sea-mew, and the hawk after its kind," (Deut 14:15). The clause "after its kind" attaches to the hawk in both versions, marking off the hawk as a category while ostrich, nighthawk, and seamew stand as single named species.
Two Lists, One Bird
The umbrella collects exactly these two verses. The UPDV does not render the bird "cuckoo" — both texts have "seamew" / "sea-mew" — but the same Hebrew bird sits in the same list-position in both Leviticus and Deuteronomy, named among the birds Israel is not to eat.
