The idea of The Numbers Game is to enter a number into the search bar of your computer and then post a selection of the photos that turn up. This week’s number is 139. Captions are on the photos.

When I was down at Pu’uhonua o Hōnaunau National Historical Park recently, I noticed, possibly for the first time, these circles in some of the fishponds. They are the nests of male Mozambique tilapia (Oreochromis mossambicus). The males hope to entice a female into laying her eggs in their nest, after which the male will fertilize them.
Tilapia were introduced to the fishponds to control mosquitoes, but like many such ideas, they have proved detrimental to the well-being of native species. Currently, efforts are underway to remove them from the ponds.

This week’s Sunday Stills challenge theme is ‘Feed the Birds.’ See more responses here.
In the top photo, this ambitious juvenile black-crowned night heron snaffled a tilapia from a large backyard pond. However, that was the easy part. I watched it for quite a while, trying to swallow the fish. It flew from the pond into a tree, then on to another one, before returning to the ground beyond some rocks. The fish was still in its beak, but no closer to reaching its stomach.
In the middle photo, a house finch chows down on the fruit of a tree heliotrope (Tournefortia argentea).
In the bottom photo, a palila feeds on a mamane (Sophora chrysophylla) seed pod. Typically, a palila will grab a pod from one place and then take it to another branch to eat it. It pins the green, immature seed pod to the branch, as in this photo, and then bashes away at it with its powerful beak. The seeds are poisonous, but palilas have developed an immunity to the toxins. The brown pods in this photo won’t be eaten by palilas. They will remain on the tree for a long time before dropping and hopefully producing more trees, though mamane seeds have quite low propagation rates.
This juvenile black-crowned night heron swooped down and snatched a large tilapia out of a pond in front of a house by the coast. Trouble is, the fish was a bit big and the heron struggled to swallow it. After working on it by the pond, the bird flew to the top of a tree where a strong wind added to its difficulties. It hopped over to a taller tree, which only made things worse, before setting down on the rocky shore nearby.
I saw the bird a few minutes later without the fish, but don’t know whether it finally managed to swallow it or gave up and ejected it. Either way it wasn’t a good day for the fish.
