    We have been colour ringing House Sparrows in Askernish since November 2010 as part of a national survey known as Retrap of Adult for Survival (RAS) which is organised by the British Trust for Ornithology (BTO). Because our birds are colour ringed, it is possible to follow them year round which means that we can gain additional information over and above that collected for RAS.

    One such thread is dispersal. We have to date received reports of our colour ringed birds from other parts of the islands as far apart as South Glendale on South Uist and Balranald on North Uist. This additional information is now beginning to give us an insight into the movements of sparrows here in the Outer Hebrides plus enabling the BTO to model the survival patterns of our birds throughout the year.

    As our first juveniles begin to disperse, this is our annual appeal that should anyone see one of our colour ringed birds, we would welcome a report. The details can be posted here, emailed to askernish.sparrows@gmail.com or by using the "contact us" tab here on this website. The colour rings are easily visible being white with a black alpha numerical code ranging from AXX to PXX

    Today (23rd June) brought two reports of sightings from South Uist. A adult female (ring not read) was seen in Lochboisdale (6km) feeding young and a juvenile male (N39) was seen in South Glendale (11km), this being a favoured destination. N39 was ringed as a juvenile on 6th June. Many thanks to Kathy Stevenson and John Kemp for reporting these sightings

    The female House Sparrow seen feeding young at Lochboisdale recently has been confirmed as L46. This bird was ringed as a juvenile on 20th June 2016 and recorded more than every other day here at Askernish until 1st November 2016. This is the first sighting of this bird since that date. Our thanks to Kathy Stevenson for this report

    Note:-
    5th July - N36, a juvenile ringed on 9th June 2017 and only seen once again on 29th June has joined L46 at Lochboisdale today

    Another sighting received today (9-July-17), that of L54 at Kilbride camp site, South Uist on 5th July. This bird was ringed as a juvenile in Askernish in June 2016, stayed until late July after which it was re-sighted in South Glendale October. It stayed there until in December and had not been seen since, until today. It looks more like a female Blackcap with some staining in it's head, perhaps it had been pollen feeding like the recent Rose-coloured Starling on Barra.
    Many thanks to Ray Morris, Jan Pritch and David Hughes for getting this to me.

    @BrianR reports that both L25 and L98 are still resident in his garden in Carinish, North Uist. These birds were first reported by Brian in November 2016 when they were first year birds. Although only 37 Km from Askernish, South Uist where they were originally ringed, this is a long distance movement for what is considered to be a sedentary species.

    While checking the resident flock of House Sparrows at North Smerclete, in amongst them was O18! This bird was ringed as a juvenile, still being fed by its parents on 2nd August 2017, and has already moved 10 Km.
