You've probably already noticed it: the feeder outside your kitchen window has turned into a small war. A rust-orange blur dive-bombs anything that gets near the ports. A second bird tries to sneak in from the juniper hedge and gets chased off before it can land. By the time you've refilled the nectar, the whole cast has changed again.
If you've lived in Aldea for a few summers, you might assume this is the tail end of hummingbird season, one last burst of activity before things quiet down for fall. That assumption is wrong, and the mistake matters if you're the kind of neighbor who takes feeders down once the fighting looks like it's winding down.
The Wrong Read on August
Here's what's actually happening. The bird you're watching defend that feeder in early August is not the same individual, and often not even the same sex, as the one you'll see there in September. Aldea's summer hummingbird traffic isn't one wave receding. It's three separate waves stacked on top of each other, and the aggressive rufous hummingbirds causing most of the drama right now are usually the first wave, not the last.
Local birders have tracked this pattern for years. Adult male rufous hummingbirds typically show up in the Santa Fe area in early to mid-July, and by late July or early August they've arrived in large numbers, according to a longtime birding column in the Santa Fe New Mexican. Each bird usually only stays a week or two before moving south. That's the group picking fights at your feeder right now.
Three Migrations Wearing One Bird's Face
The males aren't the whole story. Once they push off toward Mexico, the females follow, feeding heavily to fuel the same trip. Then come this year's juveniles, hatched in the mountains to the north, making the migration with no learned route and no experience defending a feeder. Anne Schmauss, co-owner of Wild Birds Unlimited in Santa Fe, has written that once the males clear out, "you can expect to see rufous well into September."
Here's roughly how that sequence plays out over an Aldea summer:
| Wave | Who's Arriving | Typical Window | What You'll Notice |
|---|---|---|---|
| First | Adult male rufous | Early to mid-July | Territorial dives, aggressive feeder guarding |
| Second | Adult female rufous | Late July into August | Heavy, near-constant feeding to build reserves |
| Third | This year's juveniles | August into September, sometimes later | Inexperienced birds still working the same feeders after the adults have gone |
Layer local nesters on top of that. Broad-tailed and black-chinned hummingbirds breed in Northern New Mexico and are around all summer with their own fledglings learning to feed, which is why feeder traffic in Aldea rarely thins out the way people expect once the rufous males move on.
What the Aldea Birding Group Has Already Logged
This is exactly the kind of pattern a group like the Aldea Birding Group exists to track. The ABG is a resident-run group open to birders at every level, and it maintains an ongoing list of species seen in Aldea along with a resource guide, according to the committees and groups page maintained by the neighborhood association. Members organize field trips and occasional talks, and the group's whole premise is that paying attention to what's actually moving through your own yard beats relying on a generic regional guide.
That local record-keeping is why the sequencing above isn't guesswork. It's the kind of detail that shows up when the same people are watching the same feeders across the same weeks, year after year, rather than checking in once and assuming the season is over because the fighting has calmed down.
The Other Watch List: A Bird That Never Leaves
The rufous gets the attention because it's loud about it, but the ABG's more patient project involves a bird that doesn't migrate at all. The juniper titmouse is a year-round Aldea resident, a small gray bird with a pointed crest and a scratchy chatter that lives in the neighborhood's piñon-juniper habitat. New Mexico holds close to half the species' global population, and that global population is estimated at only 180,000 individuals, a fraction of the roughly 310 million American robins worldwide, according to the New Mexico Wildlife Federation.
A resident named Don Wilson, working with Aldea's Permaculture Committee, spearheaded a nest box project for the species in partnership with Santa Fe High School's woodworking class. Peggy Darr, an Aldea resident who works as a nongame avian biologist for the New Mexico Department of Game and Fish, developed the placement plan for the boxes, and Beverly Terry of the Birding Group helped promote it. The project ties into Cornell Lab of Ornithology's NestWatch program, turning box monitoring into actual citizen science rather than a neighborhood nicety. One of those boxes, originally built for a titmouse, ended up hosting a screech owl instead, a detail captured in an earlier Santa Fe New Mexican feature on the effort.
Feeder Math for the Next Six Weeks
If you want to see the wave pattern for yourself instead of just fighting it, a few habits make a real difference:
- Add a second feeder placed out of sight of the first one. A single rufous male can't guard two locations it can't see at once, which gives broad-tailed, black-chinned, and later-arriving females and juveniles an actual chance to feed.
- Mix nectar at four parts water to one part sugar, with no dye, and change it out at least twice a week. Fresh nectar draws more consistent activity than a feeder left untouched.
- Resist the urge to take feeders down once the aggressive males clear out. Juveniles and local fledglings keep working feeders well into September, and some years activity continues into October.
Why This Particular Yard Sees It At All
None of this happens by accident. Aldea's Outdoors Committee has hosted a workshop from David Salman, the founder of Santa Fe-based Waterwise Gardening and High Country Gardens, on building water-conserving gardens suited to the neighborhood's climate. Salman's own writing on hummingbird gardens points out that New Mexico gets 60 to 70 percent of its annual precipitation in July, August, and early September, and that the monsoon rains that soak Aldea's yards are what keep the nectar-producing plants blooming right when the birds need the fuel most, a detail laid out on the High Country Gardens site.
That same wildlife-minded streak runs through the neighborhood's planting choices more broadly. Part of Aldea's open space has been managed as a certified wildlife habitat with the National Wildlife Federation, and the effort includes reintroducing the Santa Fe cholla, a cactus found only in the Santa Fe area, into the community's shared grounds. It's a small detail, but it's the reason a monsoon-season feeder fight in Aldea has three chapters instead of one. The plantings and the open space were shaped with exactly this kind of activity in mind.
So the next time the fighting at your feeder looks like it's dying down, don't read that as the season ending. Read it as the roster changing. The male that's been terrorizing your feeder since early July is booking it south, and the next round, slower and less territorial, is already working its way down through the piñon behind him.
If you're weighing a move to a neighborhood where the plantings, the open space, and even the HOA committees are built around noticing details like this, the Ricky Allen-Tara Earley Group can walk you through what makes Aldea, and the rest of Santa Fe County, worth paying attention to.
