A Full House

The poor weather over the last couple of days has brought in huge numbers of hirundines, that is swallows and martins, to Ibsley Water. there are especially very large numbers of house martin, they are impossible to count but I estimated at least 5000 today with probably 1000 swallow and at least 500 sand martin. Everywhere you looked over the water there were birds and then, scanning upward against the clouds there were many, many hundreds more. These higher birds are mostly house martin the swallow and sand martin tend to keep lower. They gather over water in an effort to find insects in weather when there are few flying elsewhere, often they pick prey directly from the surface of the lake.

The other aerial plankton feeder of summer is the swift, they mostly leave around the end of July, but a few can linger and searching through the hirundines can sometimes result in finding one and today was just such a time. Swift in September is a scarce bird, in fact in some years I don’t see one after mid August.

Other birds today included a hobby, lured in by the masses of martins as potential prey, although I did not see it catch one. The great white egret was around on and off, the ruff of the last few days was joined by another by the end of the day, when there were also 2 juvenile Arctic tern. A single black-tailed godwit dropped in for a while and there were 2 sanderling reported.

This is really not the weather for moths, so tomorrow’s planned “Moth Event” promises to be a bit of a damp squib. Today’s catch total a massive two moths! I suspect tonight may well be worse. The highlight was a fresh frosted orange, always a nice sight.

Several people mentioned the very good show of flower put on by our small patches of heather near Ivy North hide this year, in fact there at small patches of heather in several places across the lichen heath and I suspect these will expand in the coming years. All of this heather is the common ling, but we do have one plant of bell heather Erica cinerea on the reserve and this is in full flower now, somewhat after the ling has finished.

Although it is feeling very like autumn already there are still some reminders of summer out there, such as grasshoppers, I found this somewhat atypically coloured field grasshopper near the bell heather at the end of last week.

30 Days Wild – Day 5: Wet and Windy

Not a very June-like day, with increasingly strong winds and rain getting heavy by the end of the day. Not the kind of conditions to be a newly hatched, fluffy lapwing chick and not the conditions to be an adult lapwing trying to keep your chicks alive. In front of Tern hide the brood of tiny chicks I first saw yesterday turned out to be a family of three. The adults have a difficult line to tread, if they brood the chicks, keeping them warm and dry, they don’t get enough food and ultimately starve, if they let them feed they run the risk of getting wet and cold and dying anyway. So prolonged wet windy weather is very bad for chick survival, let’s hope there are enough dry breaks in the weather to give them have a chance.

Lapwing and oystercatcher chicks

As it the weather was not enough the adult lapwing are very protective of their chicks and see danger everywhere, in this case they seemed to think that the oystercatcher and her chick and the starlings were unacceptably close and needed driving off.

The oystercatcher chicks are somewhat larger now and able to cope with a bit of adverse weather. When they get to this size the adults often take charge of one chick each, watching over them and feeding them, with the chick finding a little food itself.

The poor weather brought lots of swallows, martins and swifts to feed over Ibsley Water, the numbers growing throughout the day as the conditions worsened until, by the time I closed up I estimate there were at least 1000 swifts, an amazing sight. I got a picture, but in the rain it is hard to make out the birds, I think there are probably about 75 in this shot and the whole sky was filled with them.

Resisting the Chill

Despite the cold blast, so far the nesting waders on Ibsley Water seem to be continuing to do well. The stretch of shore in front of Tern hide has a lone parent lapwing with two chicks now two weeks old and to the west of the hide there are two more broods of smaller chicks. One of these broods walked across from the restored concrete plant where they had nested. Unfortunately they did it during the middle of the day when the car park was busy and they got split up and wandering about under the brambles. I had to rescue them and carry the brood over the bank, luckily their parents were watching and quickly joined them.

As well as lapwing the shore outside Tern hide looks as though it will be hosting a pair of little ringed plover again, after a couple of years when the have been rather further away. There were a pair displaying vigorously just a few metres from the hide yesterday.

Although it was woolly hat and gloves weather yesterday the sun is now pretty strong, so out of the wind it was not too bad and at lunchtime I even saw a male orange-tip near the Centre.

The cold wind had kept the swallows, martins and swifts low over Ibsley Water in their hundreds all day, although I find it hard to imagine there were many insects even there.

The Bonaparte’s gull continues to attract visiting birders, with a supporting caste of black tern and three little gull. Remarkably another Bonaparte’s gull turned up yesterday on Bournemouth Water’s Longham Lakes site, just a few miles away. I still have not managed to better my remarkable “Record shot” of the gull, so I will sign off with one of the moth-stealing robin.
