Differences between Starlings and Blackbirds. And how to repel them…

Starlings, and blackbirds are often confused. In this article, we first explain how to distinguish them, and then recommend the best solutions for effectively repelling starlings and blackbirds when they are a problem.

First, how to tell Starlings apart from Blackbirds

As we can see in the following images starlings, and blackbirds have some physical differences:

  • the photo on the left is of a male blackbird, while
  • the photo on the right is of a starling.

In addition to the physical differences, there are also differences in their way of life. While starlings live and fly in flocks, blackbirds are less sociable birds and we see them alone or in pairs.

About Blackbirds


The Latin name for Blackbirds is Turdus Merula. Male blackbirds live up to their English name, as they have black plumage. However, females have brown plumage with spots and stripes on their chests.

Blackbirds have a bright orange-yellow beak. They have striking eyes and a soft song. These three characteristics make adult male blackbirds one of the most eye-catching birds in our gardens.

The blackbird is a resident bird in Spain. This means that they can be seen throughout the year. Blackbirds primarily feed on insects, worms, and berries or small fruits.

About Starlings


The Latin name for Starlings is Sturnus Vulgaris.

Starlings are smaller than blackbirds. They have a short tail, pointed head, and triangular wings. When viewed from a distance, starlings appear black. However, if we get closer, we will see that they have shiny plumage with a combination of blues, purples, and greens, as we can see in the photograph.

Starlings have a fast and direct flight. They are also able to run and walk confidently on the ground.

Starlings are very noisy birds. In addition, they are gregarious birds, meaning they live in large groups or flocks for much of the year. As we can see in the following video, watching a flock of starlings is an incredible spectacle.

The flock of starlings moves as a whole, contracting and expanding, rising, descending, and changing direction while always maintaining a compact shape. Unlike other flocks of birds, in a flock of starlings, there is no leader that everyone follows; each starling moves based on the movements of its closest neighbors, regardless of the size of the flock.

Starlings mainly feed on insects, fruits, berries, and seeds.


Starlings nest in holes, hollows, or cavities in virtually any location: trees, birdhouses, buildings, etc… Females lay 4 to 7 eggs. The chicks hatch after 11 to 13 days of incubation and leave the nest after 21 days. Both the male and the female are responsible for building the nest, incubating the eggs, and feeding their chicks. Sometimes starlings have 2 broods per season.

Once the breeding season is over, starlings live in large flocks. They usually choose large trees to perch on so that the entire flock can stay together, although on occasion, as we see in the photo, they choose buildings or farms, barns,…

Starling Infestations

The main problem with starlings is that they are gregarious birds, living in HUGE flocks. A single flock of starlings can reach tens of thousands of individuals.

Problems with Starlings: Structural Issues

A flock of starlings leaves a large amount of dirt in its wake, produced by the birds’ droppings. In addition to the hygienic and sanitary risks, it can cause structural problems since the uric acid found in the droppings can corrode stone, metal, and other materials.

Hygienic and Sanitary Risks Caused by Starlings

The droppings of starlings contain bacteria and fungi responsible for serious diseases such as histoplasmosis, encephalitis, salmonella, meningitis, and toxoplasmosis, among others.

Problems of Starlings for Agriculture, Livestock, Golf Courses…


As we mentioned, starlings feed on insects, seeds, and fruits. The huge flocks of starlings are a pest and a serious problem for agriculture. Starlings cause severe damage to crops, damaging vineyards and fruit fields of peaches, blueberries, strawberries, figs, apples, pears, cherries, vineyards, … And also eating the seeds planted in the fall.

In farms and livestock operations, such as cattle, pigs, sheep, or poultry farms, starlings selectively feed on the animals’ feed, causing significant economic losses. In addition, they can transmit diseases to livestock.

Similarly, starlings sometimes damage the turf of golf courses, pecking at it in search of insects and larvae.
