I live in west london, an area with not much bird life. For about 5 years we have been feeding birds and have a number of different feeders and perches. In my view there are a few things you need to take into account when luring birds.
1) a good quality seed - may cost slightly more but definitely attracts more birds. Different birds will also like different seeds and you will find this when you experiment with different seed types.
2) having areas for birds to stand on - they dont want to stand on the feeders all the time, so a small potted tree or a bush in your yard situation could also act as an attraction to the birds
3) patience - you will have an initial outlay and may not immediately see the results of birds being attracted. When the word gets around in the bird world that you have tempting offerings you will get slowly see more and more activity
4) other food - dont only have one type of seed. have one general mix one but then also have other things as these will attract other birds. The seed balls with fat are well liked as are fruit. Having these will make sure that you get the widest variety of birds possible.
5) season - at different times of year different birds will be around. We find this time of year we have the least activity. This may be because something else is naturally available in another place which they find suitable, whether it be a wild fruit or something else.
6) location - make sure that the feeding station is in a place where it is suitable. Not too close to human activity and not too close to any walls or restrictions to the birds. Also for you, make sure that there is a suitable backdrop for your pictures and that your prescence doesnt alarm them too much.
These are just a few of the important things I have noticed from feeding birds for many years. When we began we had very few types of birds and only at certain times of day. Now we have a wide range of birds and even have indian ringnecked parakeets! We have a bird prescence all day long but do notice "peak" feeding times which is important to note, as you will stand the best chance of getting a good shot at these times!
Hope my post isnt too much of a meaningless ramble and that it has some use!
