Sanhedrin 108b: What type of bird is the tushlami?

Question

The Gemara in Sanhedrin 108b says the following:

(Source from Sefaria.org)

(בראשית ו, יב) כי השחית כל בשר את דרכו על הארץ א"ר יוחנן מלמד שהרביעו בהמה על חיה וחיה על בהמה והכל על אדם ואדם על הכל א"ר אבא בר כהנא וכולם חזרו חוץ מתושלמי

[With regard to the verse:] “For all flesh had corrupted its way upon the earth” (Genesis 6:12), Rabbi Yoḥanan says: [This] teaches that [the people of the generation of the flood] mated domesticated animals with undomesticated animals, and undomesticated animals domesticated animals, and all animals with humans, and humans with all animals. Rabbi Abba bar Kahana says: And after the flood all of the creatures returned [to mate with their own species], except for the bird called tushlami, [which continued to mate with other species].

What type of bird is the tushlami? What does it look like? Where is it found?

Answer 1

Chullin 62b (as cited by Rashi on the amud you quoted) also mentions the tushlami, and there the Soncino Talmud has a note possibly identifying the bird as a wood-lark:

Possibly the crested lark, the lark, the wren, the mountain chaffinch, the wood lark, the moor-hen, the black woodpecker, and the partridge respectively. V. Lewysohn. It must be pointed out that these identifications are extremely doubtful. The suggestions can hardly be more than guesses. (Emphasis mine)

But it seems the exact identity of the tushlami is unknown. It should be noted that when you search "tushlami" into Google the first result is the Wikipedia page for the Water rail. I have no idea where the connection is made though.
