The Tyttenhanger bird report for 2015 is now available, the year produced just 129 species – the first time that the year total has fallen below 132 species since regular reporting in 2004.
Go to Tyttenhanger Site Guide for reports back to 2011.
This report is the twelfth consecutive report we have produced for the site known locally as Tyttenhanger Gravel Pits. The first report for the site was produced in 1996 (Brew, 1997) as a response to the Herts Bird Club’s Year-List Challenge of that year. Likewise, after the Hertfordshire Year-List Challenge of 2004 some of us rose to the challenge of producing a report for that year (Christian et al., 2006) and the rest is, history. Since 2004 a small (but dedicated) group has managed to produce a report every year. The format has generally followed that of the 1996 and 2004 reports with the hope that maintaining a similar layout and content would allow comparisons to be more readily made across years. The core of this, and previous, reports is the systematic list of bird observations for the year and the analysis that goes with these observations. As around 10 years is the upper limit for effectively presenting much of the available data we have also continued a transition - begun with the 2013-10th Anniversary report - to different ways of summarising the data - an outline and explanation of which can be found in more detail in the section “Data Collection, Analysis and Presentation”. Along with the full Systematic List we have continued to provide details of the recording area, public access to the site and a short review of the year. The latter includes ornithological highlights along with summaries of physical and structural changes and outstanding meteorological events. As in previous years we hope you enjoy reading this report and if you do, then we encourage you to let us know either via the email addresses below or through the Hertsbirding Yahoo! Group (see: http://groups.yahoo.com/group/ hertsbirding/). Likewise, if you did not enjoy reading it, or can think of ways of improving your enjoyment, then please let us know. Finally, as we continue to accumulate what is becoming an increasingly large body of data on the birds of Tyttenhanger, we leave you with the hope that you are encouraged to venture on-site and to submit your records through the available channels for inclusion in what will hopefully, be a long line of future reports.
