Green Island, Kume Atoll
Had planned to spend the afternoon checking Red-f. Booby + Great Frigate nests in the central roost area. I began taking egg measurements from frigate but had to stop. As soon as I freed a bird off its nest about 12 Subadult males swooped in and completely dismantled it. Several adult females, without eggs, refused to leave their nests - the seemed to realize what would occur if they left. The nests that contained eggs were not bothered but fresh empty ones were immediately deserted upon and torn up. Each bird would swoop down + pull a piece of vegetation out, fly about 50 feet before dropping the vegetation and then wheel around + return for another chop at the nest. Since I was afraid I'd totally disrupt the nesting cycle if I went around chasing all of the birds off their nests I just stopped completely.
I walked into the Scarpola toward a Red-footed Booby nest that was off by itself and the bird flew when I was about 75 feet away. While I struggled through the underbrush the frigate completely shredded the nest and broke the egg so I stopped working Red-foots, as well.
Spent the rest of the afternoon checking seals + counting more Rayson Allattons chicks in various locations for comparison with the total Chan Robbins did in February.
Saw a gull flying along the north beach around 4:15 pm but it was about 250 feet away and I couldn't tell by eye color size it was going away from me. The bird had a pure white tail + black marks on the wing tips like a King-billed Gull. She bird was an adult.
Ate cheri + played billiards until dark. It looked threatening again + the wind was gusting. Headed out to start Blue-f. Boobies, Brown Boobies, Bonin I. Petrels + anything else I can catch that is wear a band.

Kume Island,
Checked for banded birds until 12:30 am when the moon came out bright and still nearly full. As soon as the moon came out I couldn't get near anything. Checked close to 200 birds and got 165 returned. The large number of return for such a small sample resulted from working Blue-f. Booby and Rayson Allattons. For the first night since arriving here both were easy to approach. I did put off working them open + red-footed boobies because of the moonlight. I didn't want to get them all upset and nervous before that were some dark nights. Tomorrow & night I'll give the Red-footed booby a try because it will be dark until about 1:30 am.
The Blue-face Boobies, were a little hard to capture because they kept running around. Only 2 of the 78 birds handled made attempts to fly - and then half-hearted. It took a little time to round each bird up. Capturing each bird involved running around in circles after the bird until it wandered into heavy vegetation or fell into a Sherman trap. I was afraid to run because the entire area was full of burrows - didn't feel like breaking a leg tonight.
There weren't as many Bonin Boobies on the ground tonight but banded birds were easier to find. I saw the bands on all four of the birds I found tonight before the bird was picked up. She same applies to the four wedge-tails - the band on all four were visible before the birds were captured.
Brown Boobies were very spooky this evening in contrast to last night when I was able to capture 8 out of 18 sitting on the Scarpola on the edge of the north antenna field. Tonight I grabbed one bird and the rest scattered in all directions.
I almost wish I had more time here because I'm not going to finish with the albatross counts. Counting the chicks take some aim + shame because of the thick vegetation. I have about 1 1/2 full days to the 20th, and still haven't come close to completing over half the island.
During my trawl today I checked around 20 Red-tailed Procellaria today but only found one with an egg. Checking the things is very time consuming because it require crossing 15-20 feet into dense Scarpola (at times 10 feet high). She takes 5-10 minutes, capturing the bird,
