How Much Does a European Starling Weigh?

The European Starling, or Sturnus vulgaris, is a common bird species found in Europe and North America. It captivates bird enthusiasts and researchers alike due to its weight. How much does a European Starling weigh? This seemingly simple question hides many intriguing aspects.

On average, an adult starling weighs 60 to 100 grams. However, this may vary depending on age, sex, and seasonal changes. Juveniles usually weigh less, and males could be heavier than females. The season also plays a role, as food availability and breeding cycles can affect weight.

It’s important to note that individual starlings can deviate from the norm. Some male starlings may exceed 100 grams. In contrast, when food is scarce, starlings may experience weight loss.

Furthermore, scientists have discovered starlings possess an adaptive ability called phenotypic flexibility. This means their bodies adjust to environmental conditions. Dr. David Cresswell’s research at the University of St Andrews showed that urban starlings tend to be heavier than rural ones due to access to more food.

What is a European Starling?

The European Starling, scientifically known as Sturnus vulgaris, is a small songbird. It belongs to the starling family. Its vibrant feathers and melodic chirping make it a popular sight in Europe. It has a medium-sized body and measures approx. 20 cm in length with a wingspan of 37-42 cm.

Characteristics of the European Starling include dark feathers with hints of iridescent purple or green. It has a pointed bill and a short tail. This helps it with its agile flight patterns. It’s highly adaptable and can live in various habitats, like woodlands, farmlands, gardens, and urban areas.

The Starling is special for its ability to mimic sounds. It can even imitate human speech! It’s known for its impressive vocal abilities and can reproduce complex melodies. This has made it a favorite among bird enthusiasts, who often use them for vocal competitions.

If you want to attract European Starlings to your garden, try the following:

  1. Provide consistent food sources like suet or mealworms.
  2. Install nesting boxes or cavities.
  3. Avoid pesticides to keep your garden insect-friendly.
  4. Create birdbaths or shallow water features.

Importance of Knowing the Weight of European Starlings

Knowing the weight of European Starlings is important. It gives us insight into their flight patterns, feeding habits, and health. We can use it to study migration and population dynamics. Plus, it shows how environmental factors are affecting them.

For practical reasons, knowing the weight helps us design bird feeders that meet their needs. To measure, we can use a scale for small animals. Or, we can measure wing length or foot size, which can be linked to body weight.

When handling birds to weigh them, we must be gentle. That way, we can get good results without causing distress.

Methods to Measure the Weight of European Starlings

Measuring the weight of European Starlings can be done in various ways. A popular method is with a weighing scale made just for birds. It’s accurate and often used by researchers and bird lovers.

Here’s a table of methods to measure the weight of European Starlings:

Method Description
Weighing Scale A scale that accurately measures the weight of the bird.
Wing Loading Using wing area and body mass to estimate weight.
Weight Estimation Formula Using wing length and bill depth to estimate weight.
Laser Photogrammetry A non-invasive method that uses lasers to get precise measurements.

Also remember, age, sex and diet can influence the weight of European Starlings. Younger ones are usually lighter than adults. Males tend to be heavier than females. Their diet of insects and fruit can also affect their weight.

Pro Tip: Be sure to use a reliable weighing scale for birds when measuring European Starling weight. This will give you precise data for research or observation.

Average Weight of European Starlings

The weight of European Starlings can vary. Generally, they weigh 75-100 grams. That may seem light, yet it’s the norm. Let’s look at the table:

Age Weight (grams)
Hatchling 3-4
Juvenile 50-70
Adult 75-100

We see the weight rises with age. Young ones weigh 3-4 grams, juvenile 50-70, and adult 75-100.

Weight can change due to seasons, diet, and breeding. If you’re interested in this bird, there’s much to learn. Discover their behavior, migrations, and adaptability. You’ll find it fascinating!

Factors Affecting the Weight of European Starlings

Age, sex, diet, and health can all influence the weight of European Starlings. A table to illustrate this:

Factors Weight Variation
Age 60-100 grams
Sex Males: 75-90 grams, Females: 60-75 grams
Diet Varies depending on availability
Health Well-nourished birds weigh more

Age is an important factor in Starling weight. Younger birds typically weigh 60-80 grams, while adults weigh 80-100 grams. Males tend to be heavier than females, 75-90 grams vs. 60-75 grams respectively.

The diet of Starlings is also relevant. Their food depends on what’s available. A diverse diet of insects, fruits, seeds, and grains leads to healthier weight.

Finally, overall health contributes to weight. Healthy, well-nourished birds are heavier than those with health issues.

Tip: If you want to attract Starlings to your garden, provide variety in food sources. That will help them maintain a balanced diet and weight.

Why Weight Estimation is Challenging for European Starlings

Weight estimation for European starlings is difficult due to their small size and weight variation. These birds normally weigh 60-100 grams. But, their feathers are dense, making them heavier than other birds of similar size. Weight can also be affected by age, sex, and seasonal changes. Specialized techniques and equipment are needed to accurately measure the weight of a starling.

Molting cycles throughout the year cause the feathers of these birds to fall out and be replaced with new ones. This impacts the overall weight. So, it’s necessary to consider the molting stage when measuring weight.

These birds are active and strong fliers, so it’s difficult to trap them without causing stress. Traps and mist nets with bait are often used. But, capturing a representative sample can take time.

Accurate weight measurement is important for scientific studies. It provides insight into the health and fitness of the birds, as well as population dynamics and migration patterns.

Pro Tip: Consider individual characteristics, molting stage and capture methods to get more accurate results.


The European Starling is truly fascinating! They weigh an average of 75 to 90 grams, however this can vary depending on the age and sex. What’s more, they have the ability to mimic sounds! On top of that, they are social birds. It’s amazing that such a small creature can have so many captivating qualities.

Furthermore, they can fly in unison, creating mesmerizing patterns across the sky. This is known as murmuration. The Cornell Lab of Ornithology conducted a study which revealed that these birds can imitate over 20 different bird songs! From imitating robins to hawks, it’s incredible how versatile and adaptive these birds are.

These tiny creatures never fail to amaze us with their impressive skills and behaviors.
