Anas erythrorhyncha
The red-billed teal or red-billed duck is a dabbling duck which is an abundant resident breeder in southern and eastern Africa. typically south of 10° S. This duck is not migratory, but flies great distances to find suitable waters. It is highly gregarious outside the breeding season and forms large flocks.

Time the record covers
At most 129 thousand years on record.
Every occurrence read is dated to somewhere between 129 ka and 0 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.
3 occurrences of Anas erythrorhyncha on record, most of them in the Pleistocene. The Paleobiology Database records this as a living group. Bar height is expected occurrences, not a count: each fossil is spread across the span it is dated to, so a tall narrow bar means tight dating and a low wide one means loose.
When
3 occurrences- Pleistocene97%
- Holocene3%
These are dates about fossils, not the animal: the record can only begin after it arose and end before it died out, so either end may reach further. Shares are expected occurrences: a fossil dated to a span is counted partly in each period it straddles. More on what this infers.

The Paleobiology Database records 3 sites for Anas erythrorhyncha, and this reads all of them. The number is how many of those sites it was catalogued from too.
This is not a list of everything alive at the time. It is only what has come out of the same ground as this animal and been written down.

Each of the 3 occurrences read was entered from one of these publications, ordered by how many each accounts for. This is not a search for papers mentioning the name. Entries link to doi.org where the Paleobiology Database holds an identifier, and to its own record where it does not. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
