"Crossbills continue to surge in

July 3rd: 3 Lionel, 9 Galson

July 4th : 2 Luskentyre, 2+ Horgabost, 98 Northton, 18 Kyles (all south
Harris), 6 Ardvoulie Castle, 100+ Aline Forest

July 6th: c.20 plantation near council offices, Stornoway still on the
7th. One of a group handed in to me that were in an Arnol garden. This
male had been attacked by a cat and died that night in care.

If anyone gets any Xbills can they keep the corpses, or at a minimum
some feathers (esp. flank feathers). There is to be a 'stable isotope'
study on them. Idea is to see where they are coming from and how this
compares to last years birds. Tapes of calls also may be handy. It has
also been noted that there is a very high percentage of red males this
time and few (none for me) juveniles."

An irruption is when finches and other seed eaters move in large numbers in search of food. If the cone crop failed on their usual breeding grounds, Crossbills may be numerous in the UK and will arrive from the Continent from late summer, often staying to breed. There are just 1 or 2 possible Western Isles breeding records.

Crossbill's breeding season lasts from summer to the next spring to take advantage of maximum cone supplies.

In a study it was found that the number of successful breeding pairs was found to be positively correlated to the number of cones read more
