What do blackcaps eat? Blackcaps are active little birds that flit through trees and bushes looking for tasty treats. Their diet changes throughout the year to take advantage of what is available.
This article will explain all about what blackcaps like to eat. It will cover the different kinds of insects and berries that blackcaps feed on. You will learn how blackcaps use their pointy beaks to grab insects off branches and leaves. You will also find out what their favorite berries are during different seasons.
Understanding what blackcaps eat helps explain why they can thrive in many habitats. Their varied diet allows them to adapt to find plentiful food sources all year round. Read on to uncover the diverse eating habits of the blackcap songbird!
What Insects Do Blackcaps Eat?
Blackcaps eat mainly insects, especially during spring and summer. Their thin pointy beak is perfect for picking insects off leaves, twigs, and branches. What bugs and insects do blackcaps like to munch on?
Flies are a major part of a blackcap's diet. Blackcaps glean foliage to find flies to eat. They pluck adult flies as well as fly larvae right off plant surfaces. Small nuisance flies that bother humans make a tasty snack for blackcaps.
Researchers in Spain did a study observing what blackcaps living in forests liked to eat. They found that up to 65% of a blackcap's diet was made up of flies! Both forest blackcaps and blackcaps living near humans seek out flies.
Caterpillars are also prime insect prey for blackcaps. They use their slender beaks to remove caterpillars from leaves and branches. Studies show caterpillars make up around 16% of their diet.
Blackcaps search plants not just for adult insects but for insect larvae and eggs too. The larvae and eggs contain lots of nutrition in small bite-sized packages.
Blackcaps also feed on other insects like beetles, moths, ants, bugs, grasshoppers, crickets, and spiders. Any small insect that crosses a blackcap's path may end up as dinner!
Blackcaps are very flexible in the insects they eat. This helps them survive in different habitats. As certain insects become more or less available with the changing seasons, blackcaps can switch to other prey.
How Do Blackcaps Catch Insects?
Blackcaps have several techniques for catching insects:
Gleaning involves carefully plucking stationary insects directly off of leaves, branches, and trunks. Blackcaps use their thin pointy beak to precisely pick insects off foliage.
Blackcaps will fly out from branches to snatch flying insects right out of the air. They capture them mid-flight and return to their perch to eat.
Blackcaps probe into crevices and holes in wood to find insects hidden inside. Their slender beak helps them probe deep into trees and posts.
Hawking occurs when blackcaps grab insects while in flight themselves. They swoop through swarming insects and pick them off without stopping.
Blackcaps pounce on insects on the ground by dropping down suddenly from a perch above. Their sharp sight allows them to zero in on prey.
They sometimes hover briefly in front of flowers to pick off insects drawn to the nectar. Their lightweight body and quick wings let them hover easily.
These hunting techniques allow blackcaps to catch many types of insects in diverse environments. It adds flexibility to their diet.
When Do Blackcaps Eat Insects?
Insects are the main part of a blackcap's diet during spring and summer. The long hours of daylight allow them to hunt insects vigorously. Warm weather causes an explosion in the insect population, creating a bountiful food source.
Here are the reasons insects suit the blackcap diet during spring and summer:
- Abundant supply – there are simply more insects when warmer weather arrives.
- High nutrition – insects provide protein and fat blackcaps need for breeding season.
- Easy to digest – chitin in insects is easy for blackcaps' stomachs to break down.
- Quick energy – insects deliver a rapid energy boost for hyperactive blackcaps.
As fall approaches, the supply of insects starts decreasing. This leads blackcaps to switch their diet to fruits and berries in autumn and winter.
What Berries Do Blackcaps Eat?
When insect numbers decline, blackcaps switch to eating fruits and berries. Blackcaps migrate to areas with berry-producing shrubs and trees during fall. What are blackcaps' favorite berries to eat?
Mistletoe is a parasitic plant that grows on branches of other trees. When the white mistletoe berries ripen in winter, they provide a vital food source for blackcaps. These birds can devour thousands of mistletoe berries each day!
In one study, mistletoe berries made up 83% of blackcaps' diet in winter. The sticky inner pulp of mistletoe berries provides high-quality nutrition for the birds.
Blackcaps happily feed on the black berries of ivy plants. Ivy berries are small but packed with nutrients. Studies show ivy berries appear in approximately 15% of blackcaps' winter meals.
These blue berries from juniper plants are another key winter food. Like mistletoe and ivy, juniper berries remain on branches during winter when other foods are scarce.
Elderberry shrubs produce big clusters of small dark berries. Blackcaps gobble them up, dispersing the seeds. Elderberries have been found in 13% of blackcaps' winter diets in research.
The bright red berries on holly are attractive to blackcaps. They provide brilliant color against the dull winter landscape. Holly berries are nutritious but less preferred than mistletoe, ivy, or juniper.
Blackcaps occasionally supplement their berry diet with small fruits like apples, pears, figs, and tomatoes. They seem to favor sweeter fruits when available.
When Do Blackcaps Eat Berries?
Blackcaps rely heavily on berries during autumn and winter. Here's why berries suit blackcaps' needs during the cold months:
- Abundance – lots of berries stay on plants during winter
- Nutrition – berries are packed with carbohydrates and antioxidants
- Bright colors – easier for blackcaps to spot against dreary winter backgrounds
- Energy – berries provide crucial energy for blackcaps in harsh conditions
By switching to berries in fall, blackcaps remain well-fed even as insect numbers decline. This dietary flexibility is key to their success.

Why Do Blackcaps Need a Varied Diet?
The diverse diet of blackcaps provides several important benefits:
- Adaptability – Blackcaps can find food in many habitats and conditions
- Seasonal needs – Their diet shifts to fuel breeding, migration, etc.
- Nutrition – Different foods provide complete nutrition throughout the year
- Survival – Varied food sources prevent starvation if one item is scarce
- Opportunistic feeding – Blackcaps eat whichever prey is available
By alternating between insects and berries, blackcaps get the precise nutrients they require at each stage of life. Their generalized diet allows them to thrive across wide ranges and seasonal changes. This behavioral adaptation is a key reason blackcaps remain prevalent across Europe, Asia, and North Africa.
Blackcap Diet FAQs
Do blackcaps eat seeds?
Yes, blackcaps do occasionally eat small seeds like rapeseed and sunflower seeds. However, seeds make up a very minor part of their diet compared to insects and berries. They may eat more seeds in winter when other foods are scarce.
How do blackcaps find food in winter?
In winter, blackcaps seek out areas where mistletoe, ivy, juniper, and other berry producers grow. They migrate to warmer areas with more available berries. Their excellent memories help them return to plentiful winter feeding grounds year after year.
Do blackcaps eat mealworms?
Blackcaps certainly will eat mealworms, which are the larvae form of the mealworm beetle. Mealworms make a fine substitute for other insect larvae blackcaps feed on. Many bird lovers use mealworms to attract blackcaps.
What do baby blackcaps eat?
The parents of baby blackcaps work hard to bring them soft bodied insects like caterpillars and flies. As the nestlings grow, the parents start bringing larger prey. Once they leave the nest, the young blackcaps eat the same diet of insects and berries as the adults.
Do blackcaps eat bread or bird seed?
Sometimes blackcaps will sample bread or bird seed put out for other birds. However, human food makes up only a tiny portion of a wild blackcap's diet. They prefer finding natural insects and berries over bread.
In conclusion, blackcaps are remarkable for their varied diet. They alternate between plentiful insects in spring and summer, and nutrient-rich berries in fall and winter. Their pointy beak allows them to extract insects from foliage. Blackcaps consume mistletoe, ivy, juniper, elderberries and other fruit when available. This flexible, protein-rich diet allows blackcaps to flourish across diverse habitats. The next time you see a blackcap, consider the adept way it finds nutritious food all year round
