I purchased a 5 kg pack of Premium Bird Food and placed the seed in
standard cylindrical bird feeders hung from tree branches.
It's easy to spill a lot of bird seed transferring the seed from the
plastic container bag into the cylindrical bird feeder. To overcome
this problem I cut the bottom from a 2 litre plastic water bottle,
turned it upside down and used it as a funnel.
I poured a small amount of the seed into a dustpan and could see that
there was a good variety of different types of seed for the wild birds
to feed on. Once the birds (bluetits, robins and finches in my location)
got used to my shiny stainless steel and plastic bird feeders these shy
birds continually came backwards and forwards to feed. The bluetits have
fledgelings at this time of year and they were more than happy to have a
ready supply of food for their offspring.
Although carriage is expensive where I am located (rural France)I know that
can't be helped if there are no local suppliers and I just have to consider
that a necessary evil.
I will be purchasing the same seed again but this time in a much larger pack
which helps reduce the price per kilogram.
