The tables below give the status of records submitted to the Herts Rare Birds Panel that are being or have been assessed. Where records are indicated as not proven, the Panel felt that for most cases the species was probably the one claimed but that insufficient evidence was available to be 100 per cent sure of the identification and only occasionally that a misidentification had been made.

The species on the Hertfordshire list needing descriptions are shown here and should be reported using the Herts rarity description form.

Last updated on 18 October 2021.

Key: C = record in circulation, A = record accepted, NP = record not proven.
