This Summer has seen an arrival of Crossbills into the county with an increasing number of sites garnering records. Such irruptions happen periodically whenever their numbers exceed the available supply of food and birds are forced to move into new areas in search of sustenance. It took a while but I finally managed to catch up with this latest bird trend when I heard a calling bird pass overhead while butterflying in Harry's Park Wood. One of their favoured sites in the county at Wakerley has already attracted a flock and I think that a future visit there is more than likely.
Away from the Crossbill invasion it was evident that the butterfly situation is changing with fewer species on view. I did not connect with any Purple Emperors but their season may well be coming to an end. My main target today had been Purple Hairstreak but again I failed to find any, perhaps purple is just not my lucky colour! Brown on the other hand seems to be very much in vogue and both Gatekeepers and Ringlets were abundant, the latter are now looking tatty and ragged but the 'keepers still look fine. Still common but not reaching the heights of their cousins were Meadow Browns and some very fresh looking Speckled Woods. White is another colour that is very much a la mode with Green-veined in particular putting on a good show, Large Whites continue to do well while Small Whites were few and far between. Best butt of the day was a Wood White, this year has been far and away my best at this site and I really believe that they've colonised Harry's Park and look forward to seeing many more in future years.
While some species prosper it seems that others are on the way out, my only White Admiral was an incredibly tired looking individual nectaring on bramble. Likewise my only confirmed Silver-washed Fritillary was a very tatty looking female which moved on before I could grab a picture. Commas and Red Admirals remain common though Peacocks are currently outnumbering both, each bramble patch had at least one but some harboured half a dozen or more. Another species coming towards the end of their season is Large Skipper, I saw loads today but they're definitely starting to show signs of wear and tear.
Not too many odes were noted but amongst the few that I did encounter was a year first Migrant Hawker. It flew around briefly before hanging up at the Old Dry Bushes end of the complex, I don't think that I've ever seen Migrant Hawker before Common Darter in previous years but this has been a strange one. The only other species putting in an appearance was Emperor with at least four flitting along the rides. I may well have stayed later but my wife wanted to visit the Highland Gathering in Corby and I'm not brave enough to deny her. Although I was never a big fan of bagpipes despite having a Scottish heritage it seems that several pints of beer can make anything sound good!
