Reading Birds to Find Fish: How We Work Bird Piles in Hawaii

Most of the fish we find offshore in Hawaii, we find because of birds. Some days we do not even put lures out when we leave. We catch bait in the morning, run to a zone where fish were reported, and hunt for bird piles. The birds are not just telling you there is fish. They can tell you what kind of fish, and whether a pile is worth your time or not.

This post is how we decide which birds to work, which ones to drive past, and how to approach a pile without pushing the school away. A lot of it is how the captain fishing with us broke it down after a slow day where a few stray birds turned into a hooked up ahi.

The quick reads

Here is the short version of what we look for:

  • Flutter birds working one tight area, not flying fast or ranging far: something is holding bait there. Worth checking.
  • A boss bird, a sooty or a booby, shows up and stays to work, even for a few seconds: that tells me there is a fish there.
  • Flutter birds going crazy over a spot but no boss birds commit: it can be a cigarette butt or a candy wrapper in the water, not fish.
  • A pile of small white birds all spread out and going every direction: a lot of times nothing, but sometimes good sized shibis are hanging out under them. Worth one slow pass.
  • You can see the fish in the water: you stay.
  • Rough toothed porpoise move onto the pile: leave and go find something else.

Flutter birds and boss birds

The first thing is learning the difference between the small flutter birds and the boss birds, the sooties and boobies. Flutter birds are the ones you see first, and most people drive right past a couple of stray ones. But watch how they fly. If two flutter birds are working a certain area, not really flying fast and not going far away, they are on something.

The confirmation is the boss birds. When a sooty or a booby shows up and decides to stay and work for a little while, that stay is the signal. If they even stay for a few seconds, that tells me there is a fish there, versus the flutter birds going crazy over a piece of rubbish. The boss birds do not waste time on trash.

That is exactly how the ahi happened on our slow day. Picture a completely desolate ocean, no activity except a few stray flutter birds. Most people would have driven by. The captain knew by the way the birds were acting that there should be something around. The light was too low to see fish in the water, and it took a few passes to get under those birds with a live bait, but the right pass came and we were hooked up to an ahi off a pile everybody else would have ignored.

Work the pile off the lead birds, not the splash

When you commit to a pile, figure out which birds are the beaters, the head guys. All the other birds follow them. Plan your attack on where the lead birds are going, not on the whole flock milling around.

Same thing with splashes. Just because a fish splashes to your left does not mean you turn left. Watch the birds. If you overcompensate and swing left, those birds can run to your right, and now you are completely behind the pile and chasing it all over again. The birds react to where the fish are heading, so follow the birds and you stay ahead of the school.

Porpoise, whales, and sharks on a pile

Not everything working a pile is good news. On one aku run we came up on a pod of either pilot whales or melon heads sunbathing near our zone, and the honest reaction was hopefully they did not kill our spot.

Rough toothed porpoise are the clear signal to leave. When a big pile of them moved in on the aku we were working, we abandoned it. Even if we caught an aku and tried to use it for bait, they will steal it while you are reeling it in, or the second you throw it back out. The bite goes slow and you are feeding porpoise. Make one more circle, then go look for something else.

Sharks come with the life too. On that same day a small oceanic whitetip, maybe a three or four footer, ate a small fish off our line on the outskirts of a pile. We cut him loose and went back to the Aku Bones. Lots of life does not always mean lots of fish.

When the aku are small, downsize and slow down

On aku runs we mark the lines, throw two Aku Bones on the riggers, and do a high speed run up to the zone. If there are boats around when we get there, I troll a short line and slowly work circles to assess what is going on before committing to a game plan.

If small aku are jumping around the birds, we break down and go smaller: smaller lures, slower speed, shorter lines. We made three or four circles on one pile before making that change. I even ran a little pink minnow strip lure from Maui Sporting Goods that day, because pink is the best color for that. Small lures like our 5 inch Ballyhoo and the 6 inch Pee Wee Flyer are built for exactly this situation. Once you are dialed in on the pile, how you set those lines matters too, and I covered that in my post on adjusting your spread.

Put your time in

Reading birds is the difference between coming home with something and coming home with nothing. The guys who steadily catch fish do not get a bite every time they go out. They make the most of what they see on a slow day and work the pile in front of them before venturing off. That is the difference between the guys catching one or two ahi and the guys catching three or four, or catching the one when nobody else is catching.

You can get a lot of this by asking people, and I did exactly that. But you have to put your time in on the water to see it for yourself and remember it. You are not going to learn sitting on land reading magazines and watching videos. Unless you go, you will never know.

I walk you through how we build every lure at our shop in Hawaii, from the balanced lead insert and the star paper inlay to five passes of paint and the tuning box. It is the same process I showed on camera with the H-1 fish head and the 9 inch Ice Blue Moke Bullet.

Blunt Bullet Trolling Lures: Why We Shortened the Head and How I Skirt It

The blunt bullet is a shorter, fatter bullet head we designed to skitter along the surface. Here is when I run it, why I put two skirts on it instead of three, and the 7 inch skirt trick that squeezes more action out of it on a small boat.

Hook Placement for Trolling Lures: Why I Don't Try to Hide the Trailer Hook

September 23, 2026

I get asked all the time whether the trailer hook needs to hide inside the skirt. It does not, and there is a good reason: marlin swat the back of the lure first, and a hanging hook that flops at trolling speed looks like a fish tail. I also cover when to size up from 9/0 to 11/0 and 10/0 hooks based on skirt bulk.
