The Eurasian bullfinch, common bullfinch or bullfinch (Pyrrhula pyrrhula) is a small passerine bird in the finch family, Fringillidae. In Anglophone Europe it is known simply as the bullfinch (English regional, Shropshire: plum bird), as it is the original bird to bear the name bullfinch.

Taxonomy and systematics

The Eurasian bullfinch was formally described in 1758 by Linnaeus in the 10th edition of his Systema Naturae under the binomial name Loxia pyrrhula.{{ cite book | editor-last=Paynter | editor-first=Raymond A.

=Subspecies=

Ten subspecies are recognised:

  • P. p. pileata MacGillivray, W, 1837 – British Isles
  • P. p. pyrrhula (Linnaeus, 1758) – north, south central and east Europe across to central Siberia
  • P. p. europaea Vieillot, 1816 – Western Europe
  • P. p. iberiae Voous, 1951 – southwest France, northern Iberian Peninsula
  • P. p. rossikowi Derjugin & Bianchi, 1900 – northeast Turkey and the Caucasus
  • P. p. cineracea Cabanis, 1872 (Baikal bullfinch) – west Siberia and northeast Kazakhstan to east Siberia and northeast China
  • P. p. caspica Witherby, 1908 – Azerbaijan and north Iran
  • P. p. cassinii Baird, SF, 1869 – east Siberia
  • P. p. griseiventris Lafresnaye, 1841 (Grey-bellied bullfinch) – Kuril Islands and north Japan
  • P. p. rosacea Seebohm, 1882 – Sakhalin (island north of Japan)

The Azores bullfinch (P. murina), previously regarded as a subspecies of the Eurasian bullfinch, is now recognised as a separate species.{{ cite journal | last1=Sangster | first1=G. | display-authors=etal | year=2011 | title=Taxonomic recommendations for British birds: seventh report | journal=Ibis | volume=153 | issue=4 | pages=883–892 | doi=10.1111/j.1474-919X.2011.01155.x | doi-access= }}

Description

The Eurasian bullfinch is a bulky bull-headed bird. The upper parts are grey; the flight feathers and short thick bill are black; as are the cap and face in adults (they are greyish-brown in juveniles), and the white rump and wing bars are striking in flight. The adult male has a distinctive rich red chest and underparts, but females and young birds have grey-buff feathers instead. It moults between July and October, but males do not have the duller autumn plumage that is typical of some other finches.RSPB Handbook of British Birds (2014). {{ISBN|978-1-4729-0647-2}}. The song of this unobtrusive bird contains fluted whistles, and is often described as "mournful". This bullfinch's usual call is a quiet, low, melancholy whistled {{not a typo|peeu}} or pew. The song is audible only at close range. It is a weak, scratchy warbling, alternating with soft whistles. Tamed bullfinches can be taught to repeat specific melodies.{{Cite web |last=Springer |title=Songbirds turn on and tune up: Bullfinches have the brain power to learn to sing human melodies accurately |url=https://phys.org/news/2013-06-songbirds-tune-bullfinches-brain-power.html |access-date=2022-04-16 |website=phys.org |language=en}}

Distribution and habitat

This bird breeds across Europe and temperate Asia. It is mainly resident, but many northern birds migrate further south in the winter. Mixed woodland with some conifers is favoured for breeding, including parkland and gardens.

Behaviour and ecology

This species does not form large flocks outside the breeding season, and is usually seen as a pair or family group.

=Breeding=

It builds its nest in a bush, (preferably more than four metres tall and wide), mature stands of scrub, or tree, laying four to seven pale blue eggs which are mottled with red-brown. It is peculiar among the Passeriformes for having spermatozoa with a rounded head and a blunt acrosome.{{cite journal|author1=Birkhead, Timothy R. |author2=Immler, Simone |author3=Pellatt, E.

Nesting success increases progressively from April–May to June–July and August.{{Cite journal |last=Hernández |first=Ángel |date=2020-10-17 |title=Breeding ecology of Eurasian bullfinches Pyrrhula pyrrhula in an Iberian hedgerow habitat |url=https://www.tandfonline.com/doi/full/10.1080/00222933.2020.1860263 |journal=Journal of Natural History |language=en |volume=54 |issue=39-40 |pages=2613–2645 |doi=10.1080/00222933.2020.1860263 |issn=0022-2933}}

The food is mainly seeds and buds of fruit trees, which can make it a pest in orchards: in England, for centuries every parish paid a bounty for every Eurasian bullfinch killed. Ash and hawthorn are favoured in autumn and early winter.Dyda J, Symes N and Lamacraft D (2009) Woodland management for birds: a guide to managing woodland for priority birds in Wales. The RSPB, Sandy and Forestry Commission Wales, Aberystwyth, {{ISBN|978-1-905601-15-8}} If wild bird cover is planted for it, kale, quinoa and millet are preferred, next to tall hedges or woodland.
