FL flipper QA52280 FR Flipper QA52106 s165006 Sirtrack F4G Fastloc GPS tracker Carapace "Q"


“Cynthettica” had been flipper tagged some time in a previous year, but had lost the tag.

We gave her a new Front Right Flipper tag QA52106,
and Front Left flipper tag QA52280

We attached a Sirtrack F4G Fastloc GPS tracker, ARGOS number 165006, and marked the rear Carapace with the "Q" for easy ID in-water or when nesting again.

Her Curved Carapace Length (CCL) measured 103.6 cm

Nest 1) We initially found her when she nested 2.47km West of Sandy Cape on 17th November 2017.

Nest 2) She re-nested on the 30th November 2017, 3.52km West of Sandy Cape.

She swam down the east coast of the island and on 5th December was 30km south, off the Orchid Beach township:
She returned north to Sandy Cape, and on 8th December she began a swim 175km northwards, and on 12th & 13th December she visited Sykes Reef, north of One Tree Island, and east of Heron Island:

Nest 3) On 15th December moved 13km and nested on Wreck Island.
nest 4) She stayed here around Wreck Island, and nested again on 30th December.

On the 31st she moved 20km west to bask on the reef 6.6km east of NW Island, and then on the 1st January 2017 basked on the reef 700m north of NW Island.
On 4th January she swam 6km north to bask on the reef at Tyron Island, and then on the 5th went back to NW Island.

Nest 5) She attempted to nest on 15th and then nested on 16th January 2018 the NW side of NW Island.

Nest 6) After hanging about NW Island for 18 days including basking on the reef she nested here again on 3rd February.

This completed 2 known clutches on each of 3 different islands. (She may have nested prior to us finding her nesting at Sandy Cape on 17th November)

She commenced a migration on 5th February, heading west to the Queensland coast, and then turned north.

On 18th February she passed Shoalwater Bay heading north.
She passed Townsville on 7th March, Hinchinbrook Island on the 9th and on 11th March was close to Dunk Island and Mission Beach.
