it always helps to tell us where you are located. There are hardly any garden questions that can be discussed without regard to location/ climate. The site you linked is a UK site, so can we assume you are in the UK?
This is a good time to start feeding birds, for those of us in the northern hemisphere. Lots of birds eat mainly insects in the summer, but switch back to seed for the winter, when the insects are hard to find.
If you have squirrels around your yard, the ones this catalog calls "nuttery" (e.g. https://www.livingwithbirds.com/bird-fee ... y-classic/
) are the only design that has worked for me for squirrel proofing.
But this site didn't have one of the ones I think is really important, the upside down feeder:

Assuming you have goldfinches where you are. When we started putting out tube feeders, they would be swarmed by house finches and others and the goldfinches would never get any. The upside down feeder has perches over the ports instead of under, so the bird has to hang upside down. Goldfinches are perfectly happy doing that; house finches and many other birds can't. I found it for you at Amazon UK:

Amazon.co.uk also has the upside down suet feeder. If you want to put out suet, which is good to do in winter, a high energy food source, the upside down feeder is useful. Otherwise big birds including starlings, grackles, etc will just sit there and pull away at the suet until it is gone. But again, they can't use the upside down one, but woodpeckers, nuthatches, chickadees and others, like them

When we first started birdfeeding, not knowing this kind of thing, we were very disappointed, because we attracted hordes of undesirable birds, pigeons, starlings, etc. If you want it to be pleasant, you need to be selective in what you put out and how it is delivered.
Let us know what you pick and how hubby likes it. I think it is a thoughtful gift.
