Rebuttal of Johnstone, Kirby, and Kissane’s claim about a first record of Carnaby’s Cockatoo raising two broods in one season

Johnstone, Kirkby, and Kissane recently (2024) published a paper titled First record of Carnaby’s Cockatoo raising two broods in one season in Corella (48: 24-27). The paper provided a two-sentence abstract, both of which were incorrect; a poor introduction to the subject of double-brooding; an inadequate description of methods; an inadequate presentation of the results; incorrectly interpreted results; and finished with a discursive, virtually citation-free discussion.
On the evidence presented, Johnstone et al. did not demonstrate that a female Carnaby’s Cockatoo raised a second brood in one season; however, they have described a case of the same hollow being used successfully in the same season by different female Carnaby’s Cockatoos, an uncommon occurrence.
