Wild Neighbors: Common Starling (Sturnus vulgaris) On Our Portuguese Homestead
Common Name: Common Starling (European Starling; Portuguese: estorninho-malhado)
Scientific Name: Sturnus vulgaris
Animal Group: Bird
Status in Portugal: Native Palearctic species. On the mainland it is mainly a winter visitor and passage migrant.
IUCN Status: Least Concern (still declining in parts of Europe)
We first noticed them by ear. A tight, bubbling chatter mixed with stolen bits of other birds, coming from the olives and the line above the chicken run. Then we saw them: compact, dark, slightly hunched, walking rather than hopping. Today the picture got practical. We opened the run and found the usual sparrows at the feeder had company. A couple of starlings were already working our chicken food like regulars.
On this Central Portugal homestead we see them around the orchard, the short grass by the coop, and any open ground that stays damp after rain. They matter because they hunt soil invertebrates and also treat a hopper like a buffet. Learning that mix is part of living with wild neighbours.

How To Recognize Common Starling On A Mediterranean Homestead
Visual ID
Think “small blackbird that walks.” Adults are 19–23 cm, chunky and short-tailed, with a pointed bill and pinkish legs. Breeding birds look glossy black with purple and green sheen and a yellow bill. In winter the plumage is heavily speckled and the bill darkens. Juveniles are dull grey-brown. In flight the wings look triangular. On the ground they stride, they do not hop like sparrows. In Iberia, do not mix them up with the spotless starling, which looks similar but cleaner. Heavy winter spotting usually means common starling.
Sounds & Behavior
The song is a wheezy mix of clicks, whistles and copies of other species, plus a sharp flight call. They forage in tight groups and can appear at the coop the moment grain hits the pan. Around our garden they work short grass in a line, then lift together if a hawk passes. Bold, not foolish.
Tracks, Droppings & Other Signs
Tracks are small passerine prints, usually under 4 cm, often in a walking line. Droppings are typical small-bird splashes under roosts, lines and the coop ridge. Wear gloves when you clean soiled boards and do not dry-sweep old roost dust. One wet morning we followed walking tracks from the compost edge straight to the hopper. That trail told the story before we opened the gate. Seeing Sturnus vulgaris on that path made the feeder design problem obvious.
Where Common Starling Lives: Portugal and Beyond
Sturnus vulgaris is native across much of the Palearctic and winters into North Africa. It has been introduced to North America, Australia, New Zealand and elsewhere, where it is often treated as invasive. In Portugal the story is quieter. The species is native, yet on the mainland it is not the default farmyard breeder many northern readers expect. Winter flocks and passage birds are what we usually get in the centre of the country. Village nesters are often spotless starlings. The Azores hold a resident form.
IUCN lists the species as Least Concern because numbers are still huge. That hides declines in parts of western Europe, tied to grassland change and fewer soil invertebrates. On our land we see them most from the cool months into early spring. Summer sightings are fewer.
What Common Starling Eats (And What Eats Common Starling)
Diet
Omnivores with a strong insect habit. In spring they take leatherjackets, beetle grubs, caterpillars, spiders and worms. Later they shift toward fruit, olives, seeds and leftovers. That is why they found the chicken feed. We have watched them probe damp soil, then wipe the bill and move on. After fruit fall they join other birds under the figs.
Predators & Threats
Sparrowhawks and peregrines take birds from flocks. Kestrels, owls and cats take the careless. Cars take low fliers. We do not use poisoned bait. Outside Europe, control programmes target introduced flocks that damage fruit and crowd native hole-nesters. A pair at a country feeder is not that story. It is a reminder to close the grain.
Living With Common Starling On An Off-Grid Homestead
A working flock is mobile pest patrol over short grass. They also clean fallen fruit before it turns into a wasp party. The costs are local: stolen pellets, fouled perches, and noise if a big winter roost settles nearby. Adult hens are not prey. Chicks and tiny bantams should not share an open buffet with confident wild birds.
What we do:
Use a covered or treadle feeder.
Feed at a set time and lift leftover pans.
Keep compost closed.
Leave short-grazed patches so they can hunt away from the coop.
Net the fruit we cannot share.
Do not put up spare nest holes if we are trying to favour other cavity users.
If the feeder is an open banquet, wildlife will come. If insect habitat exists beyond the run, the same birds can earn their keep in the field.
Herman’s Tough Kraut Field Notes: Wild Neighbors Edition – Sturnus vulgaris
Starlings raise two questions: are they a problem, and how do we keep the feed bill from growing wings? These notes are homestead practice. For sick birds, a huge roost on a building, or legal questions, ask SPEA or a local wildlife group.
Q: Are Common Starlings dangerous to us or the dogs?
A: Risk to people is very low. Clean droppings with gloves and water. Dogs that chase flocks help nobody. Keep them out of roost trees at dusk.
Q: Will they kill chickens?
A: Adult hens, no. The real issue is stolen feed and hassle at the hopper. Give chicks a separate enclosed feeding space. For illness, ask a poultry vet.
Q: How do we stop them emptying the feeder?
A: Change the feeder. Treadle designs, narrow ports and indoor feeding cut losses. Sealed bins beat shouting at the sky.
Q: Should we attract them for pest control?
A: Short grass after rain plus nearby perches is enough. Extra grain only trains them to the yard.
Q: Common starling or spotless starling?
A: Heavy pale spotting and a darker winter bill point to common starling. Spotless birds look smoother and are the usual local breeder. Photograph in good light before you decide.
