May bird of the month – Greenfinch
Scientific name: Carduelis chloris
The aptly named Greenfinch is our bird for May, you may have also hear it called the Green Linnet and Green Grosbeak depending on the locale.
Geenfinches live to approximately 2 years.
- Feather colour – Male Greenfinches are a dull olive-green with greenish-yellow on the breast which appears bright green in the sunlight. Adult females on the other hand are duller in appearance, with less visible yellow plumage.
- Leg colour – they have a brown to pink leg colouring.
- Beak – their beaks are black-brown, short and thick.
Greenfinches typically grow to an approximate length of 15cm, with a wingspan of 26cm and weigh 28g.
Greenfinches can be recognised by their ‘chichichichichit’ continual vocals as they fly, as well as their characteristic nasal “dzwee”, particularly during the breeding season.
Breeding season usually begins in early April with their first clutches complete by the end of the month. Clutch sizes can vary from 4 – 6 eggs, with an incubation stage of about 11- 15 days and fledgling taking place 14-18 days after.
Generally a breeding pair will try for two broods.
Greenfinches can be found throughout gardens, parks woodland and farmland, usually nesting in small colonies in trees and bushes. The only areas you won’t find Greenfinches is in upland areas without trees and bushes.
A common bird now although their numbers are beginning to suffer due to an outbreak of trichomonosis, their numbers did pick up after a decline during the late 1970’s and early 1980’s.
The UK sees approx 1,700,00 breeding pairs.
What they eat:
Greennfinches are a common visitor to bird tables, particularly enjoying sunflower seeds. Due to their large bill the Greenfinch can enjoy a more varied diet, including larger seeds and peanuts.
The approximate 20% decline at the moment is mainly due to the outbreak of trichomonosis, a disease caused by the protozoan parasite Trichomonas gallinae. The disease is fatal, as a result of the birds’ difficulty swallowing food. It’s spread by birds sharing dirty feeders or drinking water, therefore we suggest a strict cleaning routine for all bird care products and the areas around them.
