New House Sparrow record

In Norway, the house sparrow (gråspurv) has been categorised as Near threatened (NT), i.e., close to being endangered in the near future. This is probably a result of a lack of breeding holes in roofs in a country where so many roofs have been improved without any thought for roof nesting birds like house sparrows and swifts (tårnseiler). I have a nest box up in the eaves which house sparrows use, although it was originally intended for swifts. Swallows have also declined in my area due to improvements to outbuildings on farms.
Therefore, I was happy this week to register the largest flock of house sparrows (90) in the garden in the course of over 35 years! They were only present for a short period on 3 different days.
