What happened to Tockus pallidirostris? (1 Viewer)

[Arbu]

I went to the Pays Dogon in Mali in 2004 where, equipped with the Collins Illustrated Checklist to the Birds of Western & Central Africa, I recorded the Pale-billed Hornbill (Tockus pallidirostris), within the range indicated in the book. Now, other than in this book, I can find no reference to this bird, only to a Pale-billed Hornbill of Southern Africa. What happened to it?

The book was pretty wrong on Red-billed Hornbills, incidentally, which I saw, although it only shows them occurring much further south, near the coast, so maybe it's wrong on this too, although it seems odd for a bird to disappear like this.

Angola and s DRCongo to Tanzania and Mozambique is the range of Pale-billed Hornbill, so definitely nowhere near Mali

Very much in Mali according to the book.

Your maps look frelled. Consider: there's an entry for "hornbill" in the second row evidently split from the prior map. The "pale-billed" map is actually for African grey, I think, as it refers to sspp a & b.

According to ebird/Clements pale-billed is now Lophoceros. Maps there indicate it's not in West Africa

I see, thanks. That would explain Red-billed Hornbill as well. It must have been African Grey that I saw then.

Also, note the text for Pale-billed Hornbill describing its habitat as "miombo". That habitat type is found nowhere near West Africa in any strict sense, though there's miombo in southeast DRC.

I think the only hornbills in Mali would be Northern Red-billed and African Grey,, when I lived in Sokoto in n Nigeria they were the only ones we used to see. I'll see if i have that Collins illustrated checklist, maybe not I suspect.

Also Western Red-billed (in the west) and African Pied (in the southwest).
