The Standlake Birder -

  My recent experiences with the hummingbirds of Costa Rica led me to ponder the why and how of the dazzling phenomena of Iridescence. As a recap, look at the two pictures of the Fiery-throated Hummingbird above.  From sideways on this Hummingbird appears emerald green but front on it is truly transformed into a veritable artists pallet of colours. To see the Fiery throat you have to be essentially face on, a few degrees either side and the fiery iridescence disappears. You would certainly be forgiven for thinking these were two entirely different birds.   I guess it’s fairly obvious that the colouration is not your run of the mill pigment colouration. In fact Hummingbirds are coloured by what’s known as structural colouration. This is a similar effect to how a prism splits light into its constituent colours. The Hummingbirds feathers have specialised pancake microscopic structures called melanosomes.  These contain little air bubbles that refract the light...

Fiery-throated Hummingbird   Now if you asked me when I was, say 18, if I would make it to three score years and ten on the 17 th  of November 2025 I would probably have laughed  in your face and said of course not. But here I was celebrating hitting the milestone in some style at the end of my wonderful Costa Rican adventure.   We had planned a leisurely departure from the Savegre complex before a day’s birding on the way back to the capital for our flight home on the next day. Our plans, however, were thrown into the air when we discovered that the only long winding road out of the complex was going to be shut for the day for road works! We hence had a hurried breakfast and departure before we were trapped for the day the wrong side of the road works. After passing the road works we all relaxed a little and looked forward to our final full days birding in paradise.    We stopped at the lovely Miriam’s Café where we enjoyed the hummingbird feeders whi...

The Great Grey Shrike and the Red-backed Shrike are two Shrikes I would expect to see every year in the UK. The Great Grey Shrike is a non-breeding scarce winter vagrant to the UK with a small number overwintering here most years. There’s been a quite showy one in the farmland hedges just outside of the small village of Fillingham in Lincolnshire for a while. So with a sunny day at last forecast for this Tuesday I was on site joining a small number of other birders just after 10 am. The sun was shining as forecast but there was a bitterly cold wind blowing and initially the Shrike was keeping to the leeward side of the hedge.   This particular chap has taken to hovering over a weedy field hawking voles. I have never seen this behaviour before and so this was something I very much wanted to see. After an hour or so of mainly preening and sheltering from the artic wind the shrike flew over the hedge into the foresaid field and started performing its acrobatics very much to the deligh...

     A combination of post Costa Rica adventure hangover and the feeling that I’m going to get wet rot every time I leave the house in this truly vile weather has made UK birding feel like a real slog so far this year. A sodden trip to the New Forest on Wednesday did nothing to lift my spirits. I did see my main target species, Firecrest, but they were wisely keeping as dry as they possibly could within their favoured Holly habitat making views less satisfactory than on previous visits. The rest of the day was pretty much a sodden write off with most birds hiding from the cold downpours.   There has been a rare American Bufflehead hanging around the Welsh coast for a few weeks which I had toyed with going to see. My experience of twitching rare ducks somewhere on a vast blank sea canvas is, to say the least, a depressing one so I had decided this one was not for me. When presumably the same bird relocated to a small lake on Anglesey the prospect of twitching it becam...

Resplendent Quetzal I had originally intended this to be my last blog on the Costa Rica trip but when I checked my photos I discovered that I had 6,000 to go through taken over the last three days of the adventure.   I hence decided to split it into more manageable two blogs. The reason for so many photos from our last lodge, Savegre, was the almost overwhelming abundance and variety of photogenic birds in the area.   Our big target bird for the 16 th   November was one of Costa Rica’s most iconic and highly sought after species, the very aptly named Resplendent Quetzal. So pre-breakfast we drove to a good local site  for them where there were many purpose-built perches photogenically covered in lichen. We got there early as Paco said it could be quite busy there and sure enough there were already other parties present creating the nearest atmosphere to a twitch that we had on the whole trip.   The Quezal twitch Within minutes of our arrival ...
