Bearded Tit Gritting Season in Full Swing

I posted in late September that the Bearded tit gritting season had started early this year. Now it is full swing, up to October 6th we have recorded 77 sightings of colour ringed birds on the trays at Leighton Moss RSPB Reserve This involves 33 different birds of these 28 are adult birds and only 5 birds of the year. This pattern of the adults starting gritting first is quite normal and as the season goes on into December the young birds become much more abundant later in the season.

Up to 9 birds have been seen at once on the three trays which are located just off the central causeway of the reserve.However it is very obvious that most birds are in pairs and as I posted before they form pairs when still in juvenile plumage. A good example of this was a pair seen together today they were first colour ringed together on 21st July 2016 and have been recorded together on 16 occasions since.Birds have also been recorded taking seed from the reed heads the reason they need grit to grind up the hard seeds in their gizzard.
Many thanks to Alan, Pauline and Judith Gallagher from Belfast for their devoted work in recording the colour sightings this week and to Steve and Jan for the early sightings.
