You know what's going to threaten way more birds than all those things put together? Climate change.

I agree that outdoor cats should be banned as well.

I think everyone has answered your question correctly so far. You can't beat plywood for strength, but it is expensive. There are middle ground alternatives.

There is Medium Density Fibreboard (MDF) which is between the two on strength but takes paint brilliantly. Many cabinet makers use this exclusively for mid range quality furniture.

Even cheaper is chipboard which is about as bad, or worse than OSB but you can get it laminated. Most very cheap furniture from places like IKEA use it and it can do a reasonable job.

All of these materials have their quirks, mainly on how you finish end grain (even plywood). Both MDF and chipboard suck at taking a screw so you have to get special screws and use them carefully. Make sure you do some research, there's plenty of YouTube videos on using the products.

It's a tough one. When we found a greenfinch with trichomonas it was heart breaking. We tried to treat it but it was too late. At the time we researched it and the RSPB advised to clean and move feeders regularly. Perhaps that's not good enough.

The next paragraph says:

The group said this has resulted in improvements to native woodlands, including natural regeneration, whilst at the same time facilitating moorland management.

Nothing like a land owner explaining to those who have very little why they should be happy with what they are given. She makes a good point that people are irresponsible, but that's due to a lack of education. Ignorant people will go wherever they want anyway.

It's a perfect example of how lobbying and misinformation can be so difficult to overcome. The impact of 'flushable' wipes is known and significant yet rules aren't put in place to stop it. I wonder why....

I'm amazed anything has caught with how wet it's been.

Unbelievable! There must be a way to track this down.
