Migrant Chiffchaff singing


Song Thrush singing

Song Thrush numbers have been down in recent years, so it is good to hear this one singing from the top of a tall Poplar tree.

Bird song in the lockdown

 These sound recordings have been made in a suburban setting in a garden in Sawbridgeworth. Previously, this would have been impossible due to background aircraft noise, even early on a Sunday morning.

We are always pleased to see Bee Orchids because sometimes they appear in large numbers only to disappear the following year. The plant has two tubers below ground and presumably can enter a form of dormancy and growth between flowering episodes. In spite of the fact that the flower resembles a bumblebee, no one has reliably observed bees pollinating these orchids. It is much more likely that they carry out self- pollination which is frequently known to be the rule with many of our orchids.

 Large Red Damselfly. RW.

 This is one of the earliest damselflies to hatch and be on the wing.

A Freshly hatched Comma Butterfly. This is really a woodland species and the underside of the beautifully coloured wings resemble dead leaves. The last generation hibernate on the bark of trees The white comma-shaped mark on the underside of the wing which gives a Butterfly its name is thought to indicate a ‘crack’ in the leaf and make the appearance much more realistic of being a dead leaf. The caterpillars will feed on Stinging nettles, Elm and Hop.

This is a dye plant with an ancient history. It produces a yellow colour which when over-dyed with Woad, produces Lincoln green.

These seem to be having a successful breeding year. Since 1990 it has suffered a decline due to the arrival of a parasitic fly Sturmia bella in 1990 which lays its eggs on nettle leaves and then they get eaten by the caterpillars.

Early Marsh Orchid.RR

 This pale coloured orchid comes into bloom mid-May.
