Wagtails to Buntings

Western Yellow Wagtail Motacilla flava

Yellow Wagtail comprises ten subspecies – nominate flava (‘Blue-headed Wagtail’) in central Europe and western Russia, flavissima (‘British Yellow Wagtail’) in Britain, north-west France, Belgium and the Netherlands, thunbergi (‘Grey-headed Wagtail’) in Scandinavia and north European Russia, iberiae (‘Spanish Wagtail’) in southern France, Iberia and north-west Africa, cinereocpailla (‘Ashy-headed Wagtail’) in Sardinia, Italy and Sicily, feldegg (‘Black-headed Wagtail’) in south-east Europe, Turkey, the Caucasus, Iran and south Central Asia, pygmaea (‘Egyptian Wagtail’) in Egypt, beema (‘Sykes’s Wagtail’) in northern Kazakhstan and southern Russia, leucocephala (‘White-headed Wagtail’) in western Mongolia and lutea (‘Yellow-headed Wagtail’) in southern Russia.

This taxonomy is not settled, however, some authors aggregating cinereocapilla, iberiae and pygmaea as ‘Southern Wagtail’ or ‘White-throated Wagtail’ M. cinereocapilla. Each subspecies is individually variable and there is extensive intergradation involving most, sometimes producing intergrades of relatively consistent appearance, for example ‘Channel Wagtail’ (flava x flavissima) and others. Occasional variant examples of one subspecies resembling another geographically distant subspecies may also occur, whilst hybridisation between Yellow and Citrine Wagtail M. citreola is also well-established.

Six subspecies are on the British List. The subspecies flavissima is a common summer visitor to Britain, whilst nominate flava and thunbergi are scarce migrants. The subspecies feldegg, iberiae and cinereocapilla are vagrants. The Central Asian forms leucocephala and beema were formerly on the British List but have now been removed, considered to be flava variants or intergrades (Kehoe 2006), whilst birds resembling lutea have also been recorded but are generally considered to be variant flavissima.

The identification of vagrant subspecies is not straightforward and, for the most part, only feasible with males, especially adults in spring. Male feldegg is striking but needs to be distinguished both from ‘black-headed’ thunbergi and from feldegg x flava/beema intergrades. The latter may be difficult to detect, showing, for example, only limited pale flecking in the supercilium or white in the throat-sides. Female feldegg can also be relatively distinctive. Male iberiae is somewhat variable and needs to be distinguished from at least white-throated first-summer male flava and from iberiae x flava and iberiae x cinereocapilla intergrades. The subspecies cinereocapilla is also somewhat variable and needs to be distinguished from at least white-throated first-summer male thunbergi and from cinereocapilla x flava and cinereocapilla x iberiae intergrades. Observers of a potential iberiae or cinereocapilla should focus on the precise supercilium, ear covert/eye-ring and throat patterns and, perhaps most importantly, the call.

Females and first-winters of vagrant subspecies pose even greater problems. In the latter case, observers should focus on overall plumage hues. Birds with a ‘cold’, ‘grey and white’ appearance reminiscent of Citrine Wagtail may be of a vagrant subspecies but may also be Eastern Yellow Wagtail.

Vocal clues are important. Birds with harsh or buzzing calls may be of a southern subspecies but may also be Eastern Yellow Wagtail (and both southern and eastern birds can also give softer calls anyway). Sound recordings would be particularly useful whilst trapped birds should have any stray feathers retained for DNA analysis.

Claims of any vagrant subspecies are welcomed but, given the complexities, BBRC has little option but to adopt a cautious approach. Claims of male (and even some female) feldegg might be acceptable if accompanied by detailed notes including on vocalisations (or sound recordings) although good photographs would be highly desirable. Claims of male iberiae and cinereocapilla should be accompanied by detailed notes, including notes on vocalisations (or sound recordings) and, preferably, by good photographs. If not attributable definitively to either subspecies, a bird might still prove acceptable as iberiae/cinereocapilla. Claims of these subspecies in other plumages, and claims of any other vagrant subspecies in any plumage, should be accompanied by a ringing recovery. (updated May 2018 AMS).

Pied Wagtail Motacilla alba

White Wagtail comprises nine subspecies – yarrellii (‘Pied Wagtail’) in Britain and Ireland, nominate alba (‘White Wagtail’) in Europe (apart from Britain and Ireland), western and central Russia and south-west Asia, subpersonata (‘Moroccan Wagtail’) in Morocco, ocularis (‘East Siberian Wagtail’) in north-east Russia and westernmost Alaska, personata (‘Masked Wagtail’) in southern Central Asia, baicalensis (‘Baikal Wagtail’) in southern Siberia and northern Mongolia, leucopsis (‘Amur Wagtail’) in Mongolia, north and east China and Korea, alboides (‘Himalayan Wagtail’) in the Himalayas and central China and lugens (‘Black-backed Wagtail’) in the Russian Far East and Japan. Some authorities recognise ‘dukhunensis’ from central Russia but this is often synonymised with alba (Alström & Mild 2003). Intergradation occurs between at least some of these subspecies. The taxonomy of the complex is debated, however. Species status for both lugens and personata has been proposed by some authors whilst others have proposed a split into nine species (Sangster et al. 1998).

The subspecies yarrellii is very common in Britain, with alba a common passage migrant and very rare breeder. Three other subspecies – leucopsis, personata and ocularis – are also now on the British List (Addinall 2005 and 2010, Hudson et al. 2009, Holt et al. 2018, Holt et al. 2022). Other subspecies are also potential vagrants to Britain, perhaps particularly subpersonata and baicalensis. The first listed has reached Portugal (Moore 1999).

The identification of adult males and most adult females to subspecies can be relatively straightforward, and first-winters of some subspecies are distinctive too. The precise pattern of the head, upperparts, flanks, breast, wing coverts, rump, uppertail coverts and tail should be noted. Aberrant adult yarrellii is a confusion risk for adult leucopsis. Vocal differences have been noted between some subspecies (Alström & Mild 2003, Robb et al. 2010).

Claims of any vagrant subspecies are welcomed if accompanied by detailed notes and good photographs. Sound recordings may also be of value A ringing recovery would provide additional evidence. (updated Oct 2023 AMS).

Snow Bunting Plectrophenax nivalis

Snow Bunting comprises four subspecies – nominate nivalis in North America, Greenland, northern Europe and north European Russia east to the Pechora, insulae in Iceland, vlasowae in northern Russia east of the Pechora and townsendi in the Bering Sea region. Intergradation between nominate nivalis and vlasowae occurs between the White Sea and the Pechora, resulting in birds of intermediate appearance (Cramp et al. 1994).

Nominate nivalis and insulae are winter visitors and rare breeders in Britain, the latter outnumbering the former. No other subspecies is on the British List but vlasowae is perhaps a potential vagrant and birds perhaps resembling this subspecies have been noted here.

The identification of vlasowae is not straightforward, resting on the extent of white in the rump in males and its extension onto the lower back and uppertail coverts. The existence of intergrades further clouds the issue, whilst some nominate nivalis from Ellesmere Island (Canada), north-east Greenland and Spitsbergen can match the appearance of vlasowae (Cramp et al. 1994).

Claims of vlasowae are welcomed if accompanied by a ringing recovery. (updated Dec 2017 AMS).
