House martin

  • characteristics: dark back, wings and tail, whitish underside
  • nourishment: mainly flying insects
  • Brood: Building breeders, up to two broods per year, up to five eggs
House martin (Delichon urbicum)

Migratory behavior

The house martin (Delichon urbicum) comes back from its wintering areas in spring. The times vary not only from place to place, but also from year to year. Most birds return between April and May.

In autumn or even in late summer the swallows move south again. The imminent train can be recognized by birds gathering on lines and masts. Among them are the young birds that have just grown up. Most house martins move away in September or early October. If it gets cold earlier, they sometimes move south as early as the end of August.

Barn swallow

  • characteristics: Blue-black upper side, light underside, throat rust-brown
  • nourishment: Flying insects
  • Brood: Building breeders, up to three broods, up to five eggs, rarely more
Barn swallows (Hirundo rustica)

Migratory behavior

Barn swallows (Hirundo rustica) leave a little later than house martins and also come back earlier. The first birds can sometimes be seen as early as March. The main flight takes place between April and mid-May.

At the end of summer, the swallows gather in their hundreds and prepare for the journey to the south, where they winter in Africa. The last animals moved away from mid to late October.

frequently asked Questions

How can you support swallows?

It is particularly important not to remove any brood nests. If the swallows make too much dirt, manure boards are an alternative. A near-natural garden supports the swallows in their foraging.

Are swallows true to location?

In fact, swallows return to their traditional breeding grounds every year. As soon as the first swallows can be seen in the sky, you can expect that your “own” swallows will also come home.

How is bird migration influenced?

Mainly due to weather and climate. If it gets cold earlier, the swallows fly to the south earlier. How long the bird migration lasts depends on the weather conditions on the way.
