Hi, Recently I've been using the bioMart package to get the ensembl gene dataset, I notice that by the function listDataset(), I could get the name of different ensembl dataset for different species, but the problem is that it seems that by this function I could only get 215 ensembl dataset for 215 different species in R, which in my dataset there are 63 species has been excluded from it, I wonder if I could find the ensembl dataset of them by other methods in R or not in R. Please tell me if there are any other method, I'll attach few species being excluded. Thanks for reading.

scientific_name: Accipiter nisus, Anas zonorhyncha, Anser cygnoides, Apteryx haastii, Apteryx owenii, Apteryx rowi, Bubo bubo, Cairina moschata, Calidris pugnax, ...

As an example,

> library(AnnotationHub)
> hub <- AnnotationHub()
  |======================================================================| 100%

snapshotDate(): 2022-04-25

> query(hub, c("Accipiter nisus","ensdb"))
AnnotationHub with 9 records
# snapshotDate(): 2022-04-25
# $dataprovider: Ensembl
# $species: Accipiter nisus
# $rdataclass: EnsDb
# additional mcols(): taxonomyid, genome, description,
#   coordinate_1_based, maintainer, rdatadateadded, preparerclass, tags,
#   rdatapath, sourceurl, sourcetype 
# retrieve records with, e.g., 'object[["AH78714"]]'

Mostly what will be available is positional data such as this rather than functional annotation such as mappings between a gene ID and a GO term. If you want those sort of data, you might look at makeOrgPackageFromNCBI from the AnnotationForge package.
