why can't I enter Burchell's Coucal
I have seen the Burchell's Coucal (Centropus burchellii) several times in South Africa over the years. Tried several times to input to Ebird, with no luck. Why? Thanks

If you really want assistance, you will need to provide much more information.

Burcell's Coucal (Centropus burchellii) is listed in an older Newman's Birds of Southern Africa, 2 of my Sasol Birds of Southern Africa and in a friends Roberts guide. The range maps change very little. I have seen this bird in the Roodeport area near Johannesburg Dec 6 1996, in the Benoni Petit Area near Johannesburg Jan 17, 2006, in the Benoni Petit area Dec 1 2016, in the Botenbok Park Nov 26 1990 and in Stillbay (Stillbaii), but I cannot locate the note with my date(s) as I saw it there several times when visiting family. Not sure what other information to provide.

Jim, I am not familiar with the species but I did a quick search on Google - it looks like Burchell's Coucal is considered a subspecies of White-browed Coucal, https://avibase.bsc-eoc.org/species.jsp?avibaseid=6C342FFF20D08A84 - therefore Burchell's does not show as an option on eBird. You could try entering your sightings as White-browed with a note in the comments that your sighting was the Burchell's subspecies.

It is listed in eBird as White-browed Coucal (Burchell's)

The ebird listing is wrong. They should list both the Burchell's Coucal and White-browed Coucal in their choices. The species look different, have different latin names. Reliance on African Birding authors would seem more prudent than a google search. But thanks anyway I am not making headway on this effort

Apparently, they were considered separate species in the past. Maybe they are indeed separate species, but it seems science (and eBird) currently recognizes both as the same species. The fact that they look different does not ipso facto make them separate species.
Taxonomy is a complicated and not always uncontroversial subject. As new facts emerge, scientists sometimes engage in lumping and splitting. The former takes two or more taxa formerly considered species in their own right and makes them subspecies of a single species. Splitting is the opposite action, whereby a single species (consisting of two or more subspecies) is split into two or more separate species. These decisions take into account studies in scientific journals which consider not only appearance, but also behavior (including vocalizations), range, possible hybridization, and increasingly, genetic distinctions, among others.
That said, not everyone agrees with all the decisions of the checklist committees.
