Sounds of oyster farm boat activity carries clearly across the bay

Sunday May 14th
2 hours after high tide (2.71m at 9:14am), cool & clear
Highlight today were 25 variable oystercatchers, roosting in the lagoon. Have not seen this many in the bay before. Rarely more than a dozen are present, usually less.
As well as:
1 Caspian tern
4 spur-wing plover
3 paradise shelduck (2 male, 1 female)
27 pied stilts
20 dotterel (mostly juvenile)
Closest observation proximity to dotterels yet. Was crouched down low on the shell
spit gap when a group of 8 juveniles got VERY curious & scampered round the observer.
"Oystercatchers also flock for winter, especially juvenile ones. There are lots on Rotoroa too and we have had a Caspian tern visiting us....might be the same one" - Eva


Wednesday May 17th
1 hour before low tide (0.56m at 5:32pm), overcast
Tide was too far out to see all the birds easily so observation was only done from shoreline going round to Pearl Bay
2 herons on the lawn
4 spur-wing plovers
1 Paradise shelduck (female)
1 pied stilt
22 oyster catchers
No dotterels noted but could easily have been present but undetected
1 banded rail was observed in the mud adjacent to the salt meadow (tide was well out), feeding at ease in the open until it sensed a presence & shot off at great speed into the ribbonwood islands.

Thursday May 25th
2 hours after high tide (3.02m at 6:09am), very low fog
13 oystercatcher
31 dotterel
35 stilts
1 Caspian tern
16 red-billed gulls
2 plovers
1 banded rail
kotare
Pied stilts were congregating within the lagoon, feeding on the edge of the main channel half way up the shellbank as it was draining out to sea. Within 1 hours of this observation thay had all flown away. Unlike the oyster catchers, the pied stilts are on site more intermittently.
Red-billed gulls arrived sporadically over an extended period. Just a few to begin with, they caused some bother for the Caspian tern.

Wednesday May 31st
2 hours after high tide (2.99m at 11:33am), extremely still, water flat calm
8 oystercatcher
25 dotterel
18 pied stilts
2 spur-winged plover
1 white-faced heron
2 paradise shelduck (pair)
Observed from the main shellbank, walking down from the landbridge. Most birds had already moved across from the lagoon & were feeding in the tideline. Able to observe dotterels at close proximity - size & colouring distinctively different between adult & juvenile.
