You know parrots.
But did you know that parrots represent only a small fraction of the world's birds?
Welcome to the passerines.
Passeriformes is the scientific order commonly called the passerines, or perching birds. And it is enormous.
Current global taxonomy recognizes roughly 6,700 passerine species, about 60% of all bird species on Earth.
“Passerine” does NOT mean “finch.”
Finches are passerines. So are canaries, waxbills, sparrows, mynahs, starlings, thrushes, wrens, swallows, crows, jays, robins, and hundreds of other birds.
They can be tiny birds weighing only a few grams, or substantially larger birds. Their diets can range from primarily seeds to insects, fruit, nectar, or combinations of these.
What they share is a particular evolutionary heritage and a suite of anatomical characteristics. One of the most recognizable is their foot: three toes directed forward and one strong toe directed backward, an arrangement specialized for perching.
Many passerines also have remarkably complex vocal anatomy. Their syrinx, the vocal organ located at the base of the trachea, allows many species to produce extraordinarily complex sounds and songs.
And this is where the word “songbird” can get us into trouble.
Not every passerine is a songbird in the everyday sense, and not every passerine lives like the little seed-eating finches we picture in a pet store.
There are thousands of species in this order, occupying an astonishing range of ecological niches.
Only a small fraction are commonly kept by people.
So why are we talking about passerines at Papayago Rescue House and adding them to our Wellness Wednesday information?
Because normally, we stay in our lane.
We are a parrot rescue. Our expertise, programs, training, husbandry, medical protocols, and education are built around captive parrots.
But sometimes a bird needs help, and there simply isn't anywhere for them to go.
Our passerines came to us because they needed a safe place, too.
That doesn't mean we pretend that caring for a passerine is the same as caring for a parrot.
It means we are willing to learn.
Passerines have complicated needs. Their anatomy, metabolism, behavior, communication, social structures, nutrition, and medical considerations can be very different from those of parrots.
So we are approaching them the same way we approach everything we do at PRH:
Learn what we know.
Identify what we don't know.
Use the best evidence available.
Work with qualified professionals when we need expertise.
Watch the consequences of our decisions.
And change our approach when better evidence emerges.
We aren't trying to become experts in every animal.
We're trying to become better caregivers for the animals who have been entrusted to us.
And right now, that includes some very small and very complicated birds.
