Not sure whether to post this under bugs or Species Dictionary.

I have just done a data-search for a polygon with the filter of Recorder 3.3 list and taxon="Mammalia" - the resulting list included records for "Twite (Carduelis flavirostris)" - obviously not a mammal, however, I can't actually see a problem in the Recorder 3.3 list, the taxonomy for Twite looks correct, so I don't know where this problem originates. Twite was the only non-mammal to be selected!
