The year started with a dozen Red-Crested Pochard, but no partridge in a pear tree, up to 140 Wigeon and a redhead Smew. Wildfowl counts were relatively high. The spring held 28 Little Egrets at roost, warblers arriving in April, Cuckoos in May and a breeding Goldeneye on adjacent Springwell Lake.
June, July and August provided a variety of warblers and sightings of up to 3 red eared terrapins. Large numbers of black headed gulls and common terns suffered from predators, amongst them coots. August highlights were a Sparrowhawk breeding nearby and Muntjac on the reserve.
In September there was no early passage of migrants until on 21st when a mixed hirundine flock obliged. A stonechat and kestrel were at Stocker’s farm. October saw increased numbers of greylag and cormorant, flocking long-tailed tits and 4 cetti’s warblers along the river with redwing and 30 red-crested pochard on adjacent Bury Lake.
November was still relatively mild with working parties at the lake in full swing. A Peregrine flew over and the BBC Country File team was on the reserve. Small numbers of Siskin arrived with the odd redpoll. Goldeneye numbers were increasing (immature males) by mid-month along with an appearance of a Great White Egret, probably the long-staying Maple Lodge individual. At month's end Chiffchaff were calling along the Colne, Red crested pochard were up to 32 on Bury Lake, there was a single Goosander on Springwell and Siskins were increasing.
December started cold and was then mild with rain and gales. By mid-month a few fieldfare and redwing were around, goldeneye were increasing up to 8, along with a few Water Rail.
