Observations: The almost windless conditions provided a rare opportunity to count divers and other birds resting on the sea, so we checked the sea area from Revtangen - Reve kai with the telescope. The count included 87 Great Northern Loons, 5 Red-throated Loons, 180 Common Scoter, 200 Long-tailed Ducks, 8 Razorbill, 7 Common Guillemot and 20 Black Guillemot.
We tried two Robinson-traps last night but only 3 species of moths caught, includingh this Powdered Quaker (Orthosia gracilis). Punktseljefly.
A long awaited addition to the lepidoptera list at Revtangen BO: This Emperor Moth (Saturnia pavonia) was attracted with a pheromone-lure. Nattpåfugløye.
A new species of Long-horn Beetle at Revtangen BO was dicovered on a furled-up mistnet, Rhagium inquisitor. Bartreløper.

This male Black-tailed Godwit was feeding close to the colourringed Curlew. The future for this popultion of the nominate subspecies breeding at Jaeren seems dark, after the Norwegian government abandoned the action plan a few years ago. So far we have seen no other initiative to save this species, seems like the governments plan is to wait until its too late - problem solved. Svarthalespove hann.
Whimbrels and one Bar-tailed Godwit past Revtangen. Småspove og en lappspove.
Gyrfalcon 2cy. Jaktfalk 2K.

Revtangen May 1st - large fall of migrants
