In this data base all by us known sighting of scarce and rare birds are listed. This includes all species with less than one hundred birds found in the Azores, and also a number of species marked rare in the Checklist of Birds of the Azores. All sightings are included, even some rejected by the Portuguese Rarity Committee (CPR). Sightings (birds) are all numbered in chronological order.
   For the same lists in a more comprehensive form (faster and more printer friendly), just with sightings but without references - please go to the Rare bird database and the Scarce and common bird database.

   We have tried to give one number for each bird which means that a bird in the same place in two different days often is presumed to be one and the same bird. In some cases (mostly larger birds) we have given a bird the same number even if the observations are made on different islands (if dates, plumage, and presumed migratory/flight direction fits). This is to avoid any double counts.
   For a number of records (especially older ones) the exact dates may be missing. Dates are then given with zeros in decades, years, or months. More information about this is often given in the full reference version (No date = 1900-00-00, before 1903 = 1902-00-00, February 1968 = 1968-02-00) et cetera.
   The data base is updated continuously but there can be some disorder concerning record numbers for recent observations. This is due to the fact that recent observations have to be checked manually if the bird might be a previous recorded individual.
   The data base shows information about references and documentation status, including judgements from CPR. References are shown selected where we have tried to, in first hand, use references concerning the first and the last sighting (sightings in between often omitted). Published and/or written sources overrides messages via SMS, e-mail and net sources, when this is possible. And references from CPR (the yearly Portuguese Bird Report) override other references where the CPR report includes exactly the same information. Judgements from CPR (approved or rejected observations) are shown for those sightings where the actual birds are involved. This often means that CPR have approved or rejected reports covering just parts of the time a bird has been seen. A long staying bird reported from September 12th to November 30th may, for example, just have been reported to CPR concerning an observation from October 10th.
