I regularly receive comments and questions about birds on this blog. I also receive comments and questions via my contact page here. I welcome these interactions with my readers.
This morning I received a question from a reader who is concerned about the finches in their garden.
We have been establishing a large area of garden for finches. Unfortunately I have a few crows now living around as they have decided my chook pen is a good restaurant. I have now cut off the egg supply but they are still around. Will they be deterring the finches from living here and are they a threat to them?
Thanks to Lee for that question.
Lee should be congratulated for these gardening aims. I assume that you have done your homework and planted bushes and grasses suitable to attract birds in general, not just finches. Finches – along with many of our smaller birds like honeyeaters, thornbills, weebills, chats, wrens and pardalotes – require a certain level of bushy shrubs to feel safe from predators. Plants like callistemons, grevilleas, melaleucas and hakeas provide protection, food sources, nesting sites and roosting sites.
Finches, being primarily seed eaters, also require a range of native grasses. These are becoming increasingly popular in gardens, not just to attract birds. Their colours and textures add significantly to the Australian feel of a native garden. Finches also love a reliable source of water, so a bird bath is essential to keep them around.
Crows, ravens, butcherbirds, currawongs and even magpies are all species that will raid the nests of smaller species of birds, including finches. They often take eggs and will also raid nests for the hatchlings. This is the natural cycle of life. Birds of prey such as falcons, hawks and kites will also raid nests, and also have the ability to take the adult birds resting or even flying.
The crows in your garden are probably resident birds. This means that they are not only present every day, they breed there or nearby. Your chook pen just provided them with an easy option. Closing access to the chook eggs was just a temporary setback to them. There must be sufficient food available for them to hang around.
Providing the finches have sufficient protection, a reliable food source, nesting and roosting sites, they should thrive in your garden. The crows and other predatory species I mentioned are a threat but probably not a deterrent.

Good gardening – and enjoy your birds.
