The River Cam has flooded the washes again to combine with the snow and make for a very slushy start to February! Despite the wet and cold weather wildfowl and Wader numbers continue to grow with Lapwing flocks looking good for the start of breeding next month. Dumbo is less impressed with the late season snow however!

]]><![CDATA[Lapwing Surveys]]>Thu, 09 Jul 2020 17:54:08 GMThttps://www.kingfishersbridge.org/wardens-blog/lapwing-surveysWith the wader breeding season drawing to a close we are now counting the flocks of fledged Lapwing chicks to record breeding success at the Reserve this year. We had a very successful season, monitoring 34 Lapwing nests and 5 Redshank nests across our wader meadows. building on our use of thermal imaging from last year to find and record nests in the spring we were also able to use it to find and track the hatched chicks.

We recorded 108 hatched chicks from the 34 Lapwing nests recorded, and 15 Redshank chicks, we know there were atleast 2 more redshank nests that we failed to find. Redhsank nest deep within grass and rush tussocks making them incredibly difficult to find even with the thermal camera

Unfortuantely due to the Coronavirus pandemic we weren't able to ring the wader chicks this year and we have to make a best estimate of chick fledging rates. The reserve currently has flocks of young lapwing up to 70 strong which would indicate a fledging rate of 2.05 chicks per pair, well over the 1.7 chicks per pair needed for a stable population.

We thought this bird had left us to continue its migration to Africa but on Oct 2nd whilst carrying out fish surveys in the project the Osprey came to check out the staff and Rick Harvey was quick enough to get this blurred (his words not mine) shot but good enough to get the leg ring code. I have now emailed Roy Dennis for the details so watch this space as they say.
It has now been in the area for at least 33 days.

I wanted to do this because one of the cygnets is white rather than the normal dirty grey/brown. This is known as a Polish morph and happens occasionally in Mute Swans and we sometimes get them in Cambridgeshire.

The female is on the left with the "Polish morph" between its two siblings.

The "Polish morph" is second from the left. Here the cygnets are 14/15 weeks old.

But seen again today by Ade Long! There has also been three juvenile Hobbies putting on a nice display catching dragonflies during the last few days.Here is a shot taken by Ian Barton recently.

The Great White Egret was feeding in the dyke in front of the hide and whilst watching it, there was a reflection on the water of a Kingfisher - it was sitting on a branch just a little further on. Later there were two Kingfishers standing on the ground on the edge of an island. That was quite unusual; normally they are up on a branch or on vegetation, but I’m guessing they were siblings as Kingfishers are usually solitary birds out of the breeding season.
Then the bird I was hoping for appeared from the south and headed straight to the lake; the juvenile Osprey on its 20th day spent in the area. Although I had seen it on the day it was first reported from a friends narrow boat I was travelling on, I had yet to see it at KFB. Not only did I see it, but I saw it catch three fish during the morning and on the first occasion watched it perched in a tree across the river for 40 minutes tucking into its breakfast.
What made it even more satisfying was later whilst I stood on the river bank overlooking the lake from the west side, a couple from Kent came along who I had met in July and as I told them about the Osprey it appeared again. It did a bit of fishing, catching one on its third attempt and flew off with it. That was nice!

Many of the breeding birds using Kingfishers Bridge rely on good fish stocks in the spring. At the end of each year we trap using double ended Fyke Nets in all of the main water bodies, to record the breeding popultions of fish giving an indication of numbers available next year.

The very dry summer conditions and exceptionally low water levels in the lake has led to concerns about surviving fish numbers.

Thank fully most fish species have faired well, with Rudd numbers only slightly lower than normal and Tench recorded for the first time in the Lake. Unfortunately Common Eel numbers are very low and may require restocking. There are still several areas to net so Eels may be available to breeding birds in other areas of the Reserve.

Floating Pennywort is growing all along the banks of the River Cam, in places growing out to mid stream. Disturbance by livestock grazing the edges and boat activity can dislodge these mats, becoming free floating. These can lodge on other fixed mats and overhanging trees to block the river surface completely.

We regularly check our section of the river and a short way upstream to recover and remove these mats where possible. This helps to minimise Pennywort build up along this section of the river and should help to prevent re-colonisation of the New Cut channel next year if the Water Buffalo manage to eradicate it.
