Stonechat or Whinchat?

Currently, the intensity of bird migration is increasing. Many Stonechat are already on the move. Their migration peaks at the end of March (upper diagram). The plumage of the females is quite variable and so it happens that certain birds with a supercilium are sometimes mistakenly identified as Whinchat. However, the latter do not appear in our area until April, with a peak at the end of April/beginning of May (lower diagram). Moreover, the first arrivals of Whinchat are usually males, which are easy to identify as such.

If you think you have a Whinchat in your binoculars at the moment, take the time to look at it carefully: the Whinchat has a longer wing (long primary projection) and above all, white at the base of the tail, which is visible in flight. The white patch on the primary coverts is not always present in females. Please note that the species is considered by the Swiss Rarities Committee in March and it is necessary to provide a good description of the bird or good photos to document a possible sighting.
