Good Evening
TEMPERATURE: Max. 11.9 ºC »» Min. 4.7 ºC »» Reset 9.0 ºC
MARINE LIFE: 3 Bald Eagles -1 juvenile.The eagles left the reserve just after 17:00. We are back to 3 geese again,I’m surprised they haven’t all left for ‘greener pastures’ now that the puddles they enjoyed so much have dried up but for a few slimy inches.Still only the one nest of Black Oyster Catcher eggs.
HUMAN INTERACTION: 5 Ecotour boats, 4 Pleasure craft. 2 of the pleasure craft were fishing in the reserve just after 13:00 but moved on with apologies after being advised of the MPA status. Picked up a drifting commercial crab trap off the east shore of Gr. Race and brought it in for disposal. This afternoon 2 College boats were in with Garry,Laura and students for a dive also Angus with Guests.

MARINE LIFE: 1 mature Bald Eagle which arrived just before noon and was harassed as yesterday until it left about 14:45. Still the 3 geese at least until 16:20 when to great honking a 4th goose flew in from the east,from all appearances this was a reunion of sorts with much beak touching and neck waving. I guess the where’s and why’s will remain a mystery.
HUMAN INTERACTION: There were 5 Ecotour boats and 2 Pleasure craft through the reserve today which although not very sunny was a very pleasant spring day.

Good Evening
TEMPERATURE: Max. 11.0 ºC »» Min. 7.1 ºC »» Reset 8.8 ºC »» Rain 0.4 mm
MARINE LIFE: 1 mature Bald Eagle. The gulls kept the big bird moving from rock to rock. Every time the eagle settled down the gulls, in groups of 5 or 6 heckled it until it flew off to another spot.Finally just after 14:00 the eagle took off towards Whirl Bay. Still 3 Geese, the loner follows the pair all around the island but if he gets any closer than 5 metres or so is driven back with much honking and neck waving.Checking the area just above the high tide line turned up 2 Black Oyster Catcher nests, which are really just depressions lined with pebbles and bits of shells and are about 20 cm across. The nest by the East Bay has 3 eggs but the nest on the north side just east of the winch house is empty -will check again tomorrow.
HUMAN INTERACTION: 5 Ecotour boats and 1 Pleasure craft through the reserve today.

Good Evening
TEMPERATURE: Max. 9.0 ºC »» Min. 6.9 ºC »» Reset 7.3 ºC
MARINE LIFE: 1 immature bald eagle landed just east at the base of the tower about 09:30, but did not stay more than 10 minutes before making it’s way over towards Bentinck Island. The wind picked up late morning and there really was not much animal activity as the westerly has been pretty constant at 45-51 knts. Most of the birds hunched down in hollows and behind clumps of grass.The 3 geese spent the day in the grass below the rock outcrop on the northeast of the island.Everything is coated with a thick layer of salt from the spray, hopefully the wind will ease off as forecasted by morning so we can clean the windows.
Needless to say there was no boat traffic today.
