Atlas code in late summer

Depending on the breeding bird species, the atlas code is no longer automatically requested by the system since July 1 or August 1. However, we would be grateful if you would continue to attach it in case of justified breeding indications (Atlas code 7 or more). This applies in particular to duck families with still dependent young.

Thank you very much for your cooperation!

Sightings from mountainous regions

Observations made above the forest line are extremely valuable due to the fact that the density of birdwatchers in the Alps and the Jura is rather low. We are also interested in observations of migrating and wintering birds at high altitudes. When submitting your observations, do not forget to check the altitude suggested by the system and correct it if necessary.

In order to get the best possible information, we ask you to locate your sightings as precisely as possible (zoom into the map until the blue and yellow dots appear, then click on the observation site; in the drop-down menu displayed, select "Add observation with exact localization"; the tip of the red pointer should point to the observation site). By doing so the altitude of the observation is automatically and precisely determined by the system. You can also add exact localizations to observation lists if you wish to (see Tipnews from 7.5.2020). If you use the NaturaList app, each of your sightings is automatically localized exactly.

We thank you in advance for your commitment and wish you fruitful hikes!

Young birds: Which atlas code to use and how to record birds age?

Towards summer, the number of immature birds increases. As they are a proof of a successful breeding, it is important to report them as correctly as possible.

The atlas code is the parameter to use. We recommend that you always use the highest possible code corresponding to the given situation. The following codes can be used to confirm the presence of young birds from the current breeding season: 13, 16 and 19.

Atlas code 19 is used when you find a nest containing eggs or young birds. It is not mandatory that you see the young birds: begging calls are sufficient, e.g. in a nesting box, or if you see adult birds carrying food to the nest at regular intervals.

Atlas code 16 is used if you see at least one adult bird carrying food for the young birds. It should not be used, however, if an adult is bringing food to the nest as part of the courtship or feeds its partner. On the other hand, this code can also be used, especially for songbirds, if you observe an adult feeding a young bird outside the nest.

Atlas code 13 refers to young birds that have left the nest. For nidicolous birds (e.g. songbirds, birds of prey), the code should only be used in the first days after the young birds leave the nest and if they are still clearly dependent on their parents. After that time, the young birds often begin extensive reconnaissance flights far away from their breeding area. As an extreme case one should mention young Black-crowned Night-Herons: they can appear in June, often still have down feathers on their head, but have been hatched outside the country. In such cases definitely do not use an atlas code! In the case of precocial birds, especially ducks, the code is used as long as the families are still easily recognizable as such. It can also be used for large fledglings until they become fledged.

In the detailed information field regarding age and sex, there are various ways to document young birds from the current calendar year: "chick", "1st year" and "immature". The term "chick" refers both to young nidicolous birds in the nest and precocial birds still wearing down feathers. Nidicolous young birds outside the nest and precocial birds which are already wearing the juvenile dress are called "1st year". Of course a chick is also a 1st year old bird and it is not wrong to call a chick that way - it is just less precise. The term "immature", on the other hand, is very imprecise and should be avoided if possible for birds that can be clearly identified as this year's birds.

Furthermore we would like to point out that it is very valuable for duck families if you indicate the number of young birds/families as well as the size of the young birds in eighths (relative to the mother) under the remarks field. See leaflet "Altersbestimmung bei Jungenten / Détermination de l'âge des canetons".

The more precise your sightings are documented, the easier it is to interpret them correctly. Many thanks for your help!

While birdwatching, be irreproachable!

With Black-winged Kite and Rosy Starling we are currently lucky enough to be able to make magnificent observations of beautiful species. We would like to take this opportunity and encourage you to observe responsibly. All of us should adopt an irreproachable behaviour at any circumstances and regardless to the species considered. A code of ethics, which has already been adopted by most of us, exists. Nevertheless, Nos Oiseaux, ornitho.ch, Birdlife Switzerland, Ficedula and the Swiss Ornithological Institute would like you to pay a special attention to the following points:

  • Do not drive on restricted roads (especially in mountainous and agricultural areas).
  • Never leave the official paths in natural reserves.
  • Never enter agriculture areas or ecological compensation zones.
  • Don't imitate the songs and calls and avoid tape-luring.
  • A picture is nothing worth if it was taken to the detriment of the bird or its environment. Moreover such pictures will never be accepted for any of our publications. Avoid taking photos of birds on the nest, as the breeding success is strongly correlated to the disturbance level. (Note that disruptions during the breeding period imply a violation of the Federal Hunting Act and can therefore be prosecuted).
  • A rare bird does NOT justify transgressing the rules cited above.

Teach your family and friends to observe the same comportment.

Thank you for your understanding and your sensitivity towards nature and birds.

New report: State of birds in Switzerland 2020

The annual publication “The State of Birds in Switzerland” summarises the results of our various monitoring projects, conducted with the support of more than 2000 volunteers in all parts of the country. The 2020 report focuses on the population trends of certain breeding bird species, for example farmland birds, owls and corvids. It also takes a closer look at trends in scarce migrants, such as Common Crane, and in winter visitors like Red Kite and Black-headed Gull. You can also explore interactive graphics from the Swiss Bird Index SBI® and the breeding bird index for each species up until 2019.

Ducks families

At this time of year more and more ducks families are observed on lakes and rivers. Apart from Mallards, all kinds of wild ducks are monitored by the "monitoring of selected species" program for which the total number of brood is counted. In order to obtain an accurate synthesis at the end of the breeding season we need precise information. For these observations it is therefore important to mention specifically the number of families present and, for each family, the amount of chicks and their size has to be specified (remarks field). The following link gives indications on how to estimate the size of chicks relatively to the size of adults: Altersbestimmung bei Jungenten / Détermination de l'âge des canetons).

Thanks in advance for these precisions. They simplify the data analysis and the monitoring of rare species.

#StayHomeandWatchOut

The campaign #StayHomeandWatchOut, which was started on many ornitho platforms in mid-March, is a great success! As we enjoy more freedom of movement again it is time to draw a final balance for this project. An international overview of the results of #StayHomeandWatchOut can be found here.

Unusually high presence of Corncrakes in the midlands
Currently, the number of Corncrake sightings in the midlands exceed by far the average quantity of the last years, see map. So far, singing individuals have been recorded on at least 8 different locations. In normal years, the occurrence is limited to 1-2 records.
 
Even if one should feel very lucky to hear this rare meadow-breeder in Switzerland, the chances this year are slightly better than usual. Should you know of a suitable meadow area in your vicinity, a nightly walk might be worthwhile. You can find a song example here and in the gallery of ornitho.ch or on xenocanto.org.
 
Still, we demand you not to use any recordings on the field. The breeding activity of these rare and endangered birds should under no circumstances be influenced or disturbanced by ornithologists. This problem should not be underestimated, especially in well-visited areas. Please behave in an exemplary manner and resist the temptation - the welfare of the birds comes first! In locations where there are indications of possible breeding, the project manager of the "Corncrake promotion project" of BirdLife Switzerland, Lucas Lombardo, will intervene actively.

Precise sightings localization

Precisely localized observations are increasingly in demand, especially during the breeding season. This precision provides essential information for protection and promotion projects.

While recording observations, it is therefore very important that it is made in the right place. Whether on ornitho.ch or on NaturaList, the tip of the red pointer on the map should always define the location of the bird/animal observed (and NOT where YOU are!). In mountainous areas, precise localizations also have the advantage that they provide automatically the right altitude, the average altitude of a square kilometer being less accurate for this purpose.

With NaturaList, all observations are recorded with pinpoint accuracy. Remember to slide the map back and forth to place the actual location of the animal beneath the tip of the red pointer. On ornitho.ch you can give a precise location in observation lists too. Simply click on the “+”sign to the left of the species name and then on the "Map" tab. Then select the correct location by clicking on the map on the corresponding place.

Thanks in advance for your commitment,

Your Ornitho.ch-Team

Minor problem with yesterday's sightings

A technical problem arose during yesterday's data imports from NaturaList. Therefore these records are not visible at the moment. But they are all stored. Biolovision plans to import them into ornitho.ch next night. We ask for your understanding and some patience!
