Priorslee Lake:  05:35 – 06:40 // 07:35 – 09:45

(103rd visit of the year)

Species added to my 2019 bird log from here
81      Little Ringed Plover
This species was actually logged on Saturday 13th March when one bird was displaying and another on the ground inside the building site to the N. This is a strictly protected species which has been present annually on this brownfield site for many year. Had these bird stayed it would have been necessary to continue to withhold the information. They seemed to find the idea of sharing with JCBs and the like uncomfortable and have apparently moved on – hence I decided to release the information. Some photos taken from outside the building site are included in this report

Bird notes from today
- single Little Grebe seen. Possibly another heard
- both Great Crested Grebes pairs seem to have one bird ‘out of action’ and on nests leaving jsut two visible on the water
- a single Barn Swallow over the W end again
- the Blackcaps are have a right scrap sorting out territories. Very difficult to be certain about numbers and birds are chasing in overlapping territories with females joining in the mayhem. Also birds are still singing from ‘new’ locations suggesting on-going arrival. I cannot believe there is room for all 16 singing birds

Nothing on the lamp poles pre-dawn

Later as the sun struggled to get out some insects appeared
- 1 wasp sp. (could not see its face marking to specifically ID it)
- >3 Melanostoma scalare (Chequered Hoverflies)
- >4 Syrphus ribesii or S. vitripennis hoverflies – indistinguishable males only
- 1 Eristalis pertinax (Tapered Drone-fly)

This is one of the two Little Ringed Plovers (LRP's) that was on the building site last Saturday (13th April) but not since. I assume it is the female as I only saw it on the ground. Apart from the calls this species can most easily be separated from the very slightly larger (Common) Ringed Plover by the obvious yellow eye-ring and its pale pinkish (rather than yellow / orange) legs.

This was the bird that was flying around calling and is therefore presumably the male. Pity they did not stay. Discussion with the site-foreman might have been challenging.

This singing warbler is a Willow Warbler. Points to note are the relatively long wings; the pale lower mandible; and the supercilium extending well behind the eye above a dark line through the eye.

Here ‘sitting up straight’ we see the yellowish wash in the throat and breast. Note too the rather thin and pointed bill – a Chiffchaff’s bill is more robust.

The eye-ring is indistinct too.

Necessarily both over-enlarged and made brighter in an attempt to see beneath the wings at the pattern on the body of this hoverfly. This looks to be a male Melanostoma scalare (Chequered Hoverfly), the yellow spots on a male being more lozenge-shaped. They are more triangular-shaped in a female.

A rather ‘cleaner’ shot of a different specimen, also a male. Note the hairs on the leaf – must be like negotiating a jungle to a small hoverfly.

This may be yet another specimen. Here the body looks red and yellow rather than black and yellow. No hoverflies have red markings like this and I can only assume this is a cast from the rather iridescent wings.

One of the Syrphus hoverflies. As this is a male – the eyes meet – it is not possible to separate S. ribesii from S. vitripennis.

This is a different specimen, and also a male.

This one settled on a small twig where it was hard to locate.

Why are things never straightforward? I think this is the dark form of a female (eyes do not meet) Eristalis pertinax or Tapered Drone-fly (the front of its head is hidden under a leaf: apologies).

It really does look ‘tapered’ here. I have no idea what it is doing. Defecating?
