Goldfinch through a partially open window (hence the flaring at the foot of the image).
I knew these stunning birds would visit the garden once I started adding niger seeds (also known as nyger or nyjer seeds) to the menu on the feeders. What I wasn't expecting was how quickly word got around the neighbourhood – the first Goldfinches were on the feeders within hours!
That, of course, in turn begs the question – how. How do they so quickly become aware of the presence of seeds they particularly love? Well, it seems it's a combination of factors and skills. They find the niger seeds through a combination of keen eyesight, observation of where other birds are feeding, and their own memory of where they have found food in the past.
They are attracted by the sight of common feeders and the high-fat, oil-rich scent of the seeds. Once one bird finds it, they often flock together, with word spreading quickly.
Goldfinches are highly social and intelligent. They often follow other birds or notice fellow flock members feeding, which guides them to new food sources.
The bright yellow colour often used for niger feeders acts as a visual attractor for them. (Mine, however, are a standard green).
As natural consumers of thistle and similar seeds, they instinctively search for high-fat, oil-rich food, which makes niger seeds highly appealing. Goldfinches remember the location of reliable, high-energy food sources and return to them regularly.
And then there is what might be called 'word of mouth'. One finch may discover the feeder, and shortly after, a whole flock will arrive.
