Watch out for Nuthatches; new online tool reveals the garden birds to look out for

01 Sep 2015 | No. 2015-49

Autumn is always an interesting time of year for garden birdwatchers and up-to-date movements of birds into gardens can now be tracked, for the first time, using the new interactive Garden BirdWatch results pages.  Developed by the British Trust for Ornithology (BTO), these tools show that Nuthatches, in particular, are taking refuge in gardens this autumn, showing their second-highest monthly peak in twenty years.

The average numbers of seed-eating bird species vary dramatically every year depending on the amount of natural food available in the wider countryside. The last two years have seen low numbers of many seed-eaters in gardens thanks to spectacular crops of seeds like beech and Sitka Spruce. This year, however, seems to be a different story.

Many seed-eating birds are already being seen in surprisingly high numbers for early autumn, suggesting that the seed crops may be poor this year. The most exciting increase is that of Nuthatch which has already been reported from a quarter of BTO Garden BirdWatch gardens, the second highest reporting rate since the survey started in 1995. Coal Tit and Siskin are also using garden resources more this autumn, both having been seen in the highest average numbers since 2012.

We know all this thanks to the astounding amount of data collected by thousands of volunteer BTO Garden BirdWatchers over the last twenty years. Until recently only a fraction of it was available online but now, thanks to recent developments in technology, the BTO have been able to make more of it available in an interactive way. Now different species can be compared on the same graph, their distribution can be mapped and different charts can be downloaded for further use.

Clare Simm, from the Garden BirdWatch team, commented "We are really excited about these new developments. These new results pages allow us to show in greater detail  the data collected by our participants and to inform, in a new way, how gardens are used by birds and other wildlife. Gardens are extremely important habitats for wildlife and now we have a resource to reflect this."
