The 2015 annual results of the BTO Garden BirdWatch show an interesting story. Thanks to a wet spring, some of our common bird species appeared to have poor breeding season, leading to low average numbers during the second half of the year. Many of the seed-eating and insectivorous species were seen in very high numbers toward the end of the year, possibly due to a poor tree-seed crop and stormy weather. It was also another year with low winter migrant numbers, which could have been driven by relatively mild winters at both ends of the year.
