Bird Feeding in Summer?

There's been a debate for years now about whether to feed birds year-round, or not. I've heard pros and cons for that, but never followed the debate really closely, as we're usually not feeding the birds (our neighbours upstairs and next door do that in winter, and I figured that would be enough).

Yesterday, though, I stumbled across a post on my Facebook feed about the dangers of feeding birds with the wrong feed in spring and summer - as that will actually kill their young. If you read German, you can read the full explanation here. For those of you not reading German, here's the short rundown:

Feeding birds during summer, especially in areas where they have little natural feed, is generally a good thing. But it has to be the right feed, else it will cause more harm than help. Suet-based feeds and fatty kernels are for winter feeding only; in summer, you should only feed small seeds from grass and wild flowers that also occur naturally in the area you live in. Another thing suitable for summer feeding is fresh or freshly killed insects. Never feed dried insects, as their salt content is too high for both adult and young birds.

One of the common statements is that the feed offered at feeding stations will only be consumed by the adult birds, who will feed "proper" things, such as insects, to their offspring. This is, unfortunately, not the case. The adults will also feed their young with the fatty seeds or suet-based feeds which are so easy to get from the feeding station. The small chicks cannot digest these foods; they block their intestines, and the chicks die over the course of several days with severe colics and constipation. (The German article linked to above also includes pictures, if you'd like to see what this looks like. Scroll down the page. Not for the faint of heart.) If they do survive, they often suffer misformations due to the malnutrition (too much fat, too little protein) from the inappropriate food. (Even winter feeding with fat food only can have negative consequences, as this study shows.)

So if you feed birds in your place - please take care to feed appropriate things only. The best way to support wild birds in your area is creating an environment where they find enough spaces to hide, build their nests, and where there are plants teeming with insect life so they can catch enough food for themselves and their brood. (Lawns are overrated anyways - go for a wild flower meadow instead. Not only will that be much more colourful, it will also save you all the work of lawn mowing...)
