Many HOS members participated in
the national Scarce Woodland Bird Survey. The survey was really about
specialist woodland birds rather than scarce birds, and there
were 28 target species including relatively common species such as
Chiffchaff, Nuthatch, and Song Thrush. Survey participants made two
visits to a couple of woodlands of their choice, and recorded on a
1:2500 scale map the birds seen or heard along a predetermined route.
The national results will help the conservation of specialist woodland
species by enabling BTO to identify the habitats used by each and to
produce recommendations for the management of woodland habitats.
Though it’s too early for any
proper national analysis, there are some interesting bits and pieces in
the Hampshire 2005 data (2006 data not yet collated).
First some statistics. There was
tremendous response and enthusiasm for the survey, and by end of
September 2005 I’d received data and maps for 61 woodlands. The surveys
involved walking some 126 kms of woodland paths and rides (twice!), and
accounted for roughly 250 hours of fieldwork by 32 different observers.
What of the birds? Perhaps not
surprisingly, Chiffchaffs and Goldcrests were the most frequently
encountered of the target species, but Blackcaps were not far behind.
And pleasingly, given the concern for the species a few years ago, there
were also very good numbers of Song Thrush. At the other end of the
scale, Turtle Doves, Nightingales, and Spotted Flycatchers were very
rare indeed, and as we might have expected, there were relatively few
Hawfinch, Willow Tit, and Lesser Spotted Woodpecker.
Although most of the survey
visits were relatively early in the season (necessary to record Lesser
Spots and Hawfinches), it would seem that Turtle Doves are now
relatively rare in Hampshire woodlands. All records would be very
welcome. Similarly, early visits will have missed Spotted Flycatchers,
but this species is in any case notoriously difficult to record in
woodland habitats; birds are invariably out of sight on dead branches
that protrude above the canopy. The Lesser Spotted Woodpecker appears to
be as rare as we feared, and though these birds are always unobtrusive
and inconspicuous, it’s worrying that we didn’t find many in a survey
specifically targeted at the species. The New Forest accounted for a
relatively high number of Redstarts, but Wood Warblers were well down on
what might have been expected there a few years ago. There were very few
Siskins recorded.
