I was sitting in our club blind near Pleasant Grove on a Saturday morning in early January, watching the sun come up over what looked like perfect habitat. Water everywhere. Spread looked good. Light wind. Clearing skies after that cold front finally pushed through.

And absolutely nothing flying.

Not a single duck in the sky.

If you hunted Northern California this season, you know exactly what I'm talking about. Didn't matter if you were at Colusa NWR, Gray Lodge, Sacramento, Yolo, Delevan, Sutter, or Little Dry Creek. Didn't matter if you were in a Butte Sink rice blind or grinding it out on public ground along the rivers. Something was off. And it stayed off from October all the way through close.

Not a complete disaster. Just... different. Different in a way that's hard to explain when you're sitting in the dark at 5:45 AM staring at empty skies over habitat that should be absolutely loaded with birds.

The refuges flooded on schedule. Rice fields held water. Spreads looked good. But the birds? Either they didn't show up the way they should've, or when they did, they were completely unpredictable. One morning you'd see a few. Next morning, nothing. Zero pattern to any of it.

This wasn't about hunting pressure getting worse or habitat disappearing. This was about weather. Specifically, three solid months of warm, southern storms that brought us everything except the one thing waterfowl migration actually needs.

Cold.

Since October, Northern California got hammered by atmospheric river after atmospheric river. But these weren't the cold, Gulf of Alaska storms that push birds south. These were warm, subtropical systems. Dumped massive amounts of rain. Kept temperatures way above where they should've been.

Want to know how wet it was? Through November, most of NorCal saw between 120% and 154% of normal precipitation. Redding recorded 19 inches of rain. 131% of normal. Red Bluff hit 154%. Ukiah saw 141%. The Shasta Basin got absolutely pounded with 6 to 8 inches during multiple storm cycles in November alone.

On paper? Looks perfect. Water everywhere. Refuges fully flooded. Private clubs flooded. Rice decomp programs running strong. The whole Sacramento Valley looked like waterfowl paradise.

But here's the problem hiding in those rainfall numbers.

Temperatures ran 10 to 20 degrees above normal through most of December. Morning lows that should've been in the low 30s were hitting the mid 40s and 50s. Days that should've had frost on the rice stubble had hunters peeling off layers by 9 AM.

If you're wondering why your usual spot near Williams was dead, why that permission piece near Maxwell wasn't holding birds, why Gridley and Live Oak areas were so inconsistent all season... this is exactly why.

Waterfowl don't migrate by looking at a calendar. They migrate because they have to. When northern staging areas stay warm and open, birds have absolutely zero reason to move south. And that's exactly what happened. All season long.

The Pacific Flyway stretches from Alaska to Southern California. What happens in British Columbia directly affects what shows up at Colusa. Simple as that.

When temps stay mild up north, shallow ponds don't freeze over. Ag fields stay accessible. Birds that should be pushing hard into California by November are still sitting comfortably in Washington and Oregon with zero reason to leave.

This isn't me speculating. Ducks Unlimited's migration reports from the Pacific Northwest documented the exact same pattern. Warmer than normal conditions in BC kept huge numbers of ducks up north way longer than usual. Oregon's Sauvie Island, one of their most popular hunting areas, saw one of the lowest duck harvests they'd had in decades.

The upstream valve just never opened. Without sustained cold weather pushing birds south in those classic big waves, California got trickles instead of floods. Those massive flights of northerners that everyone waits for? The flights we all plan our vacation days around? They simply didn't happen because the birds didn't have to leave yet.

And by the time conditions up north finally started to push some birds, it was mid to late January. Season was almost over.

All that heavy rain created another problem nobody really saw coming. Instead of concentrating birds, it spread them out.

Normal wet year? Managed wetlands and refuges hold most of the water, which means they hold most of the birds. You know where to find them. They're predictable. They have to be, because habitat is limited and concentrated in specific areas.

This year? Water showed up everywhere. Every bypass, every overflow basin, every low spot in a rice field became perfectly usable habitat. Instead of 20,000 birds stacked up tight on a refuge, you've got those same 20,000 birds scattered across three times the acreage. DU estimated close to 400,000 acres of flooded rice across Northern California greeted birds when they finally did show up. That's an insane amount of available habitat.

For hunters, that meant way lower bird densities and completely unpredictable movement. Scout a spot one day, find it empty the next. Set up where birds were yesterday, watch them land 400 yards away today. All the consistency that makes waterfowl hunting actually workable just vanished.

With abundant waste grain and invertebrates available across literally thousands of acres of flooded rice, birds had very little reason to move around. Feed, loaf, avoid pressure. They could do all of it without flying more than a mile all day. No urgency. No concentration. No patterns anyone could count on.

I hunted hard all season. Pleasant Grove area, Butte Sink, Colusa, Williams, Maxwell, Gridley, Live Oak, Knights Landing. Put in the time. Did the scouting. Yeah, it was slow. Really slow.

Large groups of geese around sometimes, massive grinds, but nothing looking to actually come down into spreads. High, moving, but not working. Duck numbers were limited everywhere I went. The consistency just wasn't there.

Rivers were swollen and full of debris from all the rain. Pushed birds off the river systems where you'd normally find some action during high water years. The usual overflow spots were either too deep, too fast, or just not holding birds because better options existed elsewhere.

Talk to anyone who hunted consistently this season and you heard some version of that same story. And it wasn't just the small operations or public land guys. DU's end-of-season assessment confirmed it across the board: tough hunting from high-dollar clubs to public areas. Nobody was immune.

Some mornings started promising. Birds moving at first light, working the spread, a few in the bag before the sun's even up. Then nothing. Complete radio silence by 8 AM. The kind of hunt where you're packing up wondering what just happened.

Other days you'd see birds flying but they just wouldn't commit. High, wide circles. Looking but not buying what you're selling. Flaring at absolutely nothing. You can see them, you can hear them, but you can't get them anywhere close to the dekes.

The hunters who actually had some success stayed mobile. Scouted constantly. Hunted less pressured spots most people weren't willing to walk to or work for. Adjusted expectations and took what each day offered instead of grinding for limits that weren't gonna happen.

But even for those guys? This season required way more work for way less reward than most of us are used to seeing.

Pintails, wigeon, and teal. Those dabblers that love shallow flooded rice took full advantage of all the expanded habitat. But they spread way out doing it. With feed and water basically everywhere, zero reason to concentrate anywhere specific.

The three-bird pintail limit was one genuine bright spot this season. USFWS approved a new interim harvest strategy that raised the daily limit from one bird to three, and it mattered on the few good days we had. California Waterfowl advocated for this change for years, recognizing that habitat changes, not hunting pressure, have been the primary factor affecting pintail populations. When you're seeing pintails and they're the most abundant species working, being able to take three instead of one is a real difference maker.

But here's the thing. In the Northern Sac Valley, DU's late-season reports noted that pintails were conspicuously absent north of the Butte Sink. That's a big deal. Normal year, pintails are everywhere up there. This year? They just weren't.

Mallards showed up but stayed totally unpredictable. Here, but not where you expected them from one hunt to the next. That consistency you can usually count on with mallards? Gone.

Geese were similar. Decent numbers of specks during brief cold snaps. Snows moving through in fits and starts. Nothing sustained. The Delta islands were apparently loaded with whitefronts and snow/Ross's geese, probably the best goose gunning in the state. But up in the Northern Valley? Grind city.

The X-Zone around Sacramento NWR closed in mid-December to protect greater white-fronted geese. Tells you something about how weird the distribution was this year.

Green-winged teal and wigeon topped the bag at most public areas in the Northern Valley. Shovelers everywhere. If you weren't seeing GWT and spooners, you probably weren't seeing much of anything.

Think of waterfowl migration like a pressure relief valve. When the north freezes up hard, the valve opens and birds flood south. This year, that valve was stuck half closed because there was never enough pressure building up north.

Birds move south when conditions force them to. Ice locks up the water. Snow covers food sources. Temps drop below what their bodies can comfortably handle. The trigger isn't just one cold night. It's sustained, hard freezing that makes northern areas genuinely uninhabitable.

When that happens, hormonal changes kick in. Biologists call it migratory restlessness. Southward movement happens in waves. You see it as those massive pushes where suddenly birds are everywhere and hunting goes from slow to incredible almost overnight.

But when northern staging areas stay 10 to 15 degrees warmer than they're supposed to be, and that's exactly what happened this fall, those biological triggers never fire. Birds that would normally be in California by Thanksgiving are still sitting in Oregon at Christmas. The whole cascade ripples down the entire flyway.

The Sacramento Valley normally holds about 44% of all Pacific Flyway waterfowl. Over 1.5 million ducks and 750,000 geese in a typical year. We're the southernmost major wintering area. Basically the last stop before way less suitable habitat in SoCal. When migration timing shifts because of warm weather hundreds of miles north of us, we feel it immediately and dramatically.

And here's the part that should concern everyone: DU's 2024-25 season review confirmed that the October through December period was the warmest in 130 years. This wasn't a blip. Historically unprecedented warm stretch that rewired migration patterns across the entire continent.

First week of January finally brought what we'd all been waiting for. A cold atmospheric river. Not another warm, subtropical system. This one came from the Gulf of Alaska and brought genuine arctic air.

Temps dropped hard into the 30s. NWS was issuing cold weather advisories for the Bay Area and interior valleys. Some areas saw their coldest morning temps of the entire season on Jan 10th and 11th.

These are exactly the conditions that push birds south. Frozen conditions up north plus storm fronts providing tailwinds for migration. That's when it happens.

Or that's when it's supposed to happen.

Early reports from hunters who got out right after that cold snap showed some improved action in certain areas. More birds moving. Better decoying behavior when you found them. But it was still inconsistent. And at that point, maybe two and a half weeks left before close.

The real question was whether it was a sustained pattern shift or just a brief cold snap in an otherwise mild winter.

Turns out it was mostly the latter.

Season closed January 28th in most zones. Youth and Veteran hunt weekends followed. Late goose season ran into early February.

And the honest assessment? It never truly turned around.

That January cold snap helped. It moved some birds. Certain areas saw improvement, especially in the Grasslands Ecological Area down south, where GWT numbers picked up and hunters with access to large, shallow ponds found pintails working midday and afternoon shoots. Kern NWR was quietly putting up some of the best birds-per-hunter averages in the state, close to three-bird averages, mostly gadwalls and shovelers. Public areas like the Gadwall Unit, Kesterson NWR, and West Bear Creek were giving up decent hunts.

But in the Northern Sacramento Valley, where most of us hunt, where the tradition runs deepest and the expectations are highest? It stayed slow. Wigeon and green-winged teal topped the bag. Goose hunting was slow everywhere except select spots holding massive flocks of snow and Ross's geese. Public areas were very slow, with Colusa NWR yielding the top daily averages.

The Suisun Marsh held birds. Shovelers, green-winged teal, wigeon. But dense fog stifled morning hunts for weeks, and where afternoon hunting was allowed, that's where the action was. The Delta islands were covered with geese. Best goose gunning in the state, honestly.

But for Northern Valley duck hunters? The season just sort of... ended. Not with a bang. Not with that late-season magic push we all kept hoping for. It just ended.

Here's where it gets really interesting. And a little concerning if you're paying attention.

The 2025 State Waterfowl Surveys showed significant declines in key species. Mallard breeding estimates came in at 382,588 birds. Down 26% from 2024. Lowest since 1993. Let that sink in.

Northern pintails fell 22% to 138,529. Blue-winged teal declined 15%. Green-winged teal dropped 24%. Gadwall slipped about 3%. Shovelers dipped 6%.

There's context here. The 2025 breeding season had decent habitat conditions. Near to above-average precipitation in Northern California. Full water allocations for wetlands and rice in the Sacramento Valley. Infrastructure was there for a productive nesting season. The issue is that these numbers represent a continuation of a multi-year downward trend that started almost a decade ago.

One bright spot in the data: diving ducks told a completely different story. Redheads set a record at 295,424, up 23% and 136% above the long-term average. Canvasbacks climbed 14%. Scaup up 26%. And in the Northeastern stratum, Canada geese surged 81% year over year.

But for the species most of us target in flooded rice country? The dabblers? The trajectory is concerning.

It's not just fewer birds in the strap, though that's obviously part of it. A season like this costs you in ways that add up fast.

Gas money from driving all over the valley scouting. Colusa one morning, checking Delevan in the afternoon, running up to Maxwell to look at fields, back down to Knights Landing to see if the rivers dropped. Those miles add up when you're trying to stay on top of where birds actually are. Or aren't.

Vacation days burned hoping conditions would align, only to sit through slow hunts that don't produce. Time off work you can't get back, spent in a blind watching empty skies.

The wear on your gear and your enthusiasm. The mornings you drag yourself out of bed at 3:30, knowing the odds aren't great, but going anyway because you're a waterfowl hunter and that's what we do.

And if you hunt with your kids or have a young dog you're trying to train? A season like this is especially tough. You want them to experience success. See what good waterfowl hunting looks like. Understand why we love this. Instead they're learning that hunting means long, cold sits for very few birds. That's not the introduction you hope to give them.

The frustration is real. The disappointment is legitimate. Pretending otherwise doesn't help anyone.

Every difficult season ends up being an education if you're paying attention. This one taught us a few things worth remembering.

Precipitation alone doesn't create great hunting. Temperature matters just as much, maybe more. We saw in real time how warm conditions hundreds of miles north of us can fundamentally alter what shows up locally. We learned that abundant habitat can sometimes work against the concentration and predictability that makes hunting productive.

We also got reminded that waterfowl hunting is never guaranteed. Requires real flexibility. Genuine persistence. Acceptance of conditions completely beyond our control. The best hunters aren't the ones complaining about tough seasons. They're the ones who adapt and find ways to have success anyway, even when success means a two-bird day instead of a limit.

This season wasn't bad management. It wasn't declining habitat. It was weather patterns that didn't align with what migration requires, combined with breeding population numbers trending the wrong direction.

The birds are out there. They're just not always where we need them when we need them. That's the deal we signed up for.

So where does this leave us?

The three-bird pintail limit is something to watch. USFWS said the impact would be assessed over several seasons to determine if it becomes a long-term strategy or gets modified. Research continues to suggest habitat changes rather than hunting are the primary driver of pintail population dynamics. Good news for continued liberal limits, but the underlying population decline is still a concern.

Habitat infrastructure in the Sacramento Valley remains world-class. When birds do come, the welcome mat is out. Refuges are well-managed. Rice country is flooded and functional. Private clubs maintain excellent habitat. California Waterfowl and DU continue to fight for water rights, wetland protections, and hunter access. That advocacy work matters more than ever coming off a season like this one.

But the bigger question, the one nobody can answer right now, is whether the warm fall pattern we saw in 2025-26 becomes the exception or the new normal. Two consecutive seasons of historically warm October-through-December temperatures. Two consecutive seasons of delayed and diminished migration into California. That's not a pattern anyone wants to see continue.

If you're a Northern California waterfowl hunter, here's what I'd say. Don't let one tough season, or even two, push you away from the sport. The great seasons absolutely still come. When cold weather hits right and migration fires on schedule, there's nothing on earth like waterfowling in the Sacramento Valley. Nothing.

But also? Be realistic about what you're seeing. Pay attention to the population data. Support the orgs doing the conservation work. Stay flexible in how and where you hunt. And maybe stop planning your entire season around what worked five years ago.

I'll be out there in October. Same spots. Same early alarm. Same pre-dawn thermos in the dark while I wait for shooting light.

Because that's what we do.

Some years you get the birds. Other years you get the education. This year, most of us got the education. And honestly? That might end up being the more valuable thing.

See you in the fall.

Tight lines and good hunting,

Casey
