Why supporting bird life in your garden?

Many people enjoy attracting birds in their garden just for the pleasure of bird watching or hearing them sing. Now birds certainly also have an useful ecological role for gardeners such as hunting harmful insects or bringing nutrients to the earth with their droppings.

Bird population have damatically decreased in Europe mostly due to the destruction of their habitat. Most biologists encourage people to help maintaining bird populations offering them food an nesting opportunities until better times come: In the event that humans will be able to change their relationships to the environment and to restore a natural habitat for birds, the artificial maintaining of bird populations would have at least saved species from exctincting.


Supplementary feeding

Observations by biologists have demented assumptions that supplementary feeding could have detrimental effects on birds (birds becoming "lazy", leaving from looking for food by themselves, risk that parents would feed their young with unsuitable food, hygiene problems at feeding facilities, etc.). As a matter of fact, birds keep searching actively for food by themselves as long as they find some and know exactly what kind of food is suitable for their young. Experiments have shown that supplementary feeding of birds had positive effects on populations. For more details, refer to my references below.

Therefore, feel free to set up feeding facilities in your garden or on your balcony, but you should also be aware of other environmental aspects like the following.

Some environmental aspects of bird supplementary feeding

  • If you collect some food during a walk in nature, be careful not to plunder the site of your collection: The local birds need this food too and you should leave enough seeds to allow sufficient reproduction of the plants. Suitable seeds for collection are seeds of Dandelion (Taraxacum), Nettle (Urtica) and thistle (Cirsium). Nevertheless, you could rather reserve some space to those plants in your garden.
  • When looking at the labelling of the bird feeding sacks in supermarkets, I could not find out where they originate from, only the company responsible for the "bringing into circulation". According to NABU and Lohmann (see references below), bird feeding packs offered in shops are mostly imported from Eastern-European countries and the import of bird-feeding mixes is suspected to be the main cause of the spreading of the common ragweed (Ambrosia artemisiifolia) that was brought originally from America to Europe. The plant is spreading rapidly in Europe and provokes violent allergic reactions in people affected by hay fever. Preferably prepare your own bird feeding mix or check for the "Ambrosia controlled" symbol on the packaging. Some consumer organisations will inform you on the Ambrosia pollen contents of commercial bird feeding mixes (like "Öko-Test" in Germany). Beside of this, importing bird-feeding articles from far away is linked with pollution due to transportation.
  • Considering the huge sacks of sunflower seeds for birds that are sold in supermarkets, commercial bird feeding articles probably originate from monocultures. Now, monocultures and industrial agriculture are main enemies of birds: Due to the removal of bush rows / walls delimiting field to obtain large cultivated fields lead to the loss of habitat (shelter and source of food), the to tightly arranged crop rows preventing birds landing on fields, etc. are thought to be the main cause of bird population decrease. Thus, buying those products, we only give birds an ersatz of what we have withdrawn them.

You will therefore understand that bird supplementary feeding might make sense in order to maintain bird populations that are at risk, but that a better solution is to preserve or restore their habitat, as far as possible. If you have a garden, you have to some extent an opportunity to lay it out in order to attract them and to grow plants that can offer shelter and food. The next section will offer hints on simple measures to support bird life in your garden.

How to support bird life in your garden

  • Trees, bushes, and climbing plants can offer a shelter and nesting opportunities as well as food supply to birds.
  • Weeds are a habitat for insects which are in turn a source of food for many species of birds. Some birds feed their young on weed seeds, like the seeds of Dandelion (Taraxacum). Therefore, do not clear frantically all weeds in you garden and allow some wild space in it.
  • Plant seed-producing flowers such as sunflowers in your garden and leave them on stem or on the floor for the winter.
  • Bushes carrying berries like juniper can offer a nice meal to birds that rather feed on soft food.
  • Do not use chemicals (pesticides) in your garden: These can poison or affect the reproduction of birds especially in birds that feed on insects, due to bioaccumulation.
  • Do not place feeding facilities near windows because of the risk of collision for birds who are not able to recognise glass panes or are deceived by glass reflection. Equip windows with bird protection glass which bear UV-rays reflective structures that are perceptible to birds without impeding your living comfort.
  • Make your own compost and make leaf heaps (e.g. to protect your plants in the winter) in which insects and worms (thus food for birds) proliferate.
  • Have a drinking and bathing facility available, such as a small pond or a bird bath.
  • Beekeepers usually clear drone larvae from their hives in the spring: contact a local beekeeper to obtain some of the removed combs and hang them in your garden since these larvae offer a precious source of food, especially for spring broods.
  • Have some sand available near feeding facilities: birds ingest coarse sand grains that facilitate the digestion of seeds.
