As Mark has been very busy covering a number of recent developments in British wildlife conservation this past week, the Sunday book review he normally publishes is this week more of a Tuesday book review. However he more than makes amends for being a couple days late by focusing this new column on the recent publication of the British Trust for Ornithology’s State of the UK’s Birds 2017 and a particularly handy volume published a decade ago with which to compare the finding of the BTO’s new report: A Climatic Atlas of European Breeding Birds.
