And even better to have two! Which is what we saw today hunting insects over Ivy Lake when we went to put out another of the tern rafts. These sickle-winged falcons winter south of the Sahara and fly north to breed along with their favourite prey, swallows and martins. Watching them swooping to catch flying insects is a fantastic experience, you can only marvel at their mastery of the air, one of the great sights of summer.
The tern rafts are gradually being deployed, so far the terns have looked interested but failed to occupy any of the rafts before they have been dominated by pairs of black-headed gull. It is always a problem getting the timing right and this is why I deploy the rafts one or two at a time, at some point the terns must surely be ready to take control of one.
There have been at least 30 common tern around regularly and they have been doing courtship flights and bringing food, so I think they should be ready to settle soon. So far there has been little sign of much tern passage, apart from a few beautiful black tern, the biggest group so far being 5 on Sunday afternoon. Little gull are usually birds of passage that stay at most a day or so , which makes the fine adult that has been frequenting Ibsley Water for several days something of an exception. It was there again today, although I don’t think anyone saw the Bonaparte’s gull. Other birds have included a few dunlin and common sandpiper and last week a bar-tailed godwit.
In recent posts we have featured a number of pictures of lapwing chicks, sadly I don’t think any of them have survived. This season has been a good one for the number of pairs and in general hatching success has been quite good, but the chicks have been disappearing fast. I think a combination of dry weather and predators is the cause. Dry conditions mean the chicks get brought to the lakeshore to seek food, as all their favoured puddles are gone, unfortunately the shore is regularly patrolled by fox and other predators, as it regularly has washed up food in the shape of dead birds and fish. The foxes may not be actively seeking the chicks but they will not refuse one should they come across it. Sadly a similar lack of success is befalling the little ringed plover, but at least they will continue to try and may yet succeed before the summer is out.
The cold winds are making moth trapping a slow business, with few species flying, although we have caught an eyed hawk-moth and a couple of poplar hawk-moth recently.
