Communication of the Swiss Rarities Committee

The Swiss Rarities Committee (SRC) has published its annual report for 2020. This report has been published in December 2021 in “Nos Oiseaux” (in French) and in “Ornithologischer Beobachter” (in German). Both versions can be downloaded from the SRC website

The highlights of 2020 in Switzerland were the first Oriental Turtle-Dove Streptopelia orientalis, the first Brown Shrike Lanius cristatus, the third Roseate Tern Sterna dougalli (the second since 1900), the third Blyth’s Reed Warbler Acrocephalus dumetorum, the fourth Pallas’s Leaf Warbler Phylloscopus proregulus, the 11th record of Terek Sandpiper Xenus cinereus (2 individuals, 8th record since 1900) and the 10th Audouin’s Gull Larus audouinii. The Icelandic subspecies of the Black-tailed Godwit Limosa l. islandica was recorded for the first time in 2019 and again in 2020. The first Woodchat Shrike of the subspecies Lanius senator badius has also been registered. The first wild Black Vulture Aegypius monachus (category A) and Purple Swamphen Porphyrio porphyrio originating from an introduced population (category C) were recorded. A record number of 10 Black-winged Kites Elanus caeruleus has been reported, and a new influx of Rosy Starlings Pastor roseus has occurred, with 61 sightings of 139 individuals. New breeding records of Zitting Cisticola Cisticola juncidis (5) and Moustached Warbler Acrocephalus melanopogon (1) have occurred.

The SRC would like to thank the collaborators who transmitted homologation forms, sometimes also for more common species. The detailed descriptions, often completed with pictures, considerably facilitated the work of the committee.

Be careful! Birds are getting older...

The bird’s age is commonly measured in calendar years (i.e. the "official birthday" of every bird is the 1st January). It means that since the 1st January 2022, birds born in 2021 are in their second year (and not in their first year). Those born in 2020 are now in their third year and so on... Keep it in mind if you specify the bird’s age in your sightings!

However, this information is optional. Indeed, the determination of age and sex is often far from obvious, sometimes impossible, or only if the bird is in hand.

The golden rule is therefore to use these boxes only when you are absolutely certain of the determination. It is better to leave them empty than to enter false information.

Thank you very much!

Communication of the Swiss Rarities Committee

The Swiss Rarities Committee (SRC) has published the minutes of its last meeting, held on 18 November 2021, on the SRC website (www.vogelwarte.ch/src). Among the reports accepted during that meeting are the 1st record of Steppe Eagle, the 1st record of Western Sandpiper, the 5th record of Iberian Chiffchaff, the 10th record of Rustic Bunting, the 11th record of Greenish Warbler, the 12th and 13th records of Audouin's Gull, the 15th and 16th records of Pygmy Cormorant, the 21st record of Long-legged Buzzard, the 18th record of Lesser Spotted Eagle since 1900 and the 1st record of Cinereous Vulture in category A.

In order to facilitate its administrative work, the SRC recommends to send the rarities reports and photographic proofs as soon as possible and if possible in electronic format (preferably as pdf file) to the following address: sak@vogelwarte.ch. The form can be downloaded from the SRC website (www.vogelwarte.ch/src-downloads). In the normal case, the person who discovered the bird is responsible for the sighting documentation.

The SRC thanks you for your collaboration and wishes you many interesting winter observations!

Bulletin of the Ornithological Information Service from the Swiss Ornithological Institute

Twice a year, the Swiss Ornithological Institute publishes the so-called “ID-Bulletin”. This report summarizes the most interesting bird sightings and developments on the Swiss Avifauna over the last months. The main information source of this report are the sightings posted on ornitho.ch. Additionally, updates of the different monitoring projects of the Swiss Ornithological Institute are presented as well as interesting ring founds. The latest issue can be found here (in French or German).

We wish you an enjoyable reading!

How to document a sighting?

Some sightings are marked with a yellow triangle and an exclamation mark. Such a symbol means that the sighting is unexpected and needs to be documented more precisely. It may be related to a rare species, an unusual date or an unusual observation site.

The main goal of documenting a sighting is to produce a detailed description of what you have observed:  Each and every evidence concerning the size, appearance, feathering, calling, song, behaviour, the observation conditions, and diagnostic criteria eliminating similar species are needed. Additional proofs like pictures, drawings, video sequences and sound recordings are most welcome. Such documentation is to be done using the official rarities homologation form, which is then sent to the Swiss Rarities Committee (sak@vogelwarte.ch) with the additional proofs. This expert group assesses whether the sighting is correct and sufficiently documented or not to be taken into account in the scientific literature. Sightings accepted by this committee are additionally marked with a green hook behind the yellow triangle.

If such a bird remains in the same place for many days, it is not necessary to describe each and every observation in detail. Yet it is very important to document the first and the last observation date as well as the different individuals present during that time if more than one individual is present. In the normal case, the person who discovered the bird is responsible for the sighting documentation.

An insufficient documentation is the most frequent reason for a sighting to be rejected by the Swiss Rarities Committee. In almost all such cases the description is too poor or even missing. Sentences such as "I know this species very well", "the song was typical" or "the bird was identical to the one pictured in my identification book" are definitely not part of a description. Insufficiently documented observations are not taken into account at all, in any scientific studies. They are marked with a red exclamation point and remain visible only for the person who submitted it, yet not for the other users of ornitho.ch.

In order to guarantee a long term quality of the data published on ornitho.ch, we need you to document your unusual observations as completely as possible. Keep in mind to send your documentation as soon as possible to the Swiss Rarities Committee. Thanks in advance for your commitment on ornitho.ch!

Query by troop size

You have seen 100 white storks and want to know if that is an exceptional number? Recently, it has become possible to filter by troop size on ornitho.ch with the "search engine". To do this, limit the number of individuals accordingly in the "Other restrictions" tab. This now makes it easy for you to find out whether such large groups are regularly reported.
