Boyd’s Bible Dictionary:
(eye feathered cock). An import from Tarshish (1 Kings 10:22; 2 Chron. 9:21). The peacock of Job 39:13 should be ostrich.
Concise Bible Dictionary:
These were imported by Solomon along with ivory and apes. The Hebrew word tukkiyyim is very similar to the Cingalese name of the peacock, tokei, and this is doubtless the bird intended (1 Kings 10:22; 2 Chron. 9:21). The common peacock is the Pavo cristatus. In Job 39:13 is the word renanim, and this is supposed to refer to the ostrich.
