1) Individuals with white patches at the base of the primaries. Superciliosus is, by contrast, the scarcest of the four forms, with a very few records of single birds, mostly in May in the far southwest. All adults show all-dark bills (though sometimes with a faintly blue-grey or paler base), while the tails of many (but not all) individuals appear very slightly graduated, with slightly longer central than outer tail feathers. At least in 2003 and 2004, small but significant numbers of rather more "sandy-backed" individuals have been noted, comprising very approximately 10% of Brown Shrike recorded in mid- to late May. This shrike is mainly brown on the upper parts and the tail is rounded. 5. It appears prone to vagrancy, and has been recorded in Australia (first accepted on Christmas Island in 1988), Western Europe (apparently ca 8 times between 1985 and 2003), and North America (first in 1977: Gibson, 1981). Although this bird looks more mature than a first year (juvenile) bird but it has insufficient criteria for an adult female.”, Dato’ Dr Amar-Singh HSS Scientific Name: Lanius cristatus Malay Name: Tirjup Biasa Chinese Name: 红尾伯劳 Range: Found from Siberia, Northeast China, Northern Japan to Korea, wintering to the Indian Subcontinent, Southern China, Taiwan and Southeast Asia. I have many more images of the front if there is any request. The Brown Shrike had apparently gone first thing, so after 2 hours of lugging heavy 500mm f4 and tripod around the site at Warham Greens, I went to Wells Woods, just managed to get a spot in the rather pricey car park, the place was rammed with people. It then turned its attention to me to see if I was suitable for a meal and came real close, allowing for an opportunity to get close up images. In Kazhakstan, I must have been a really lucky birder to find hybrid pairs containing Brown and Isabelline Shrikes in close proximity to each other, and both of these paired with Red-backed!". Incubation is probably mostly or entirely by female, about 15-17 days. Ear coverts This subspecies, like lucionensis, appears clearly different in the field from all subspecies of Isabelline. Separation from the various taxa of Isabelline Shrike is potentially significantly more problematic. Young “Possibly an adult female but could be a 1st winter moulting into an adult.” Dato’ Dr Amar-Singh HSS Ipoh, Perak, Malaysia 18th March 2018 Location: Ipoh, Perak, Malaysia Habitat: … Continued The distinction is not easy to use in the field but has been tested with breeding birds in Japan where the female can be identified from the presence … Grayish white to pale buff, with spots of brown and gray often concentrated at large end. Although the vast majority of Brown Shrike appear to show dark lores, at least five females seen in the spring of 2004 (out of less than 50 noted as such) showed rather plainer and paler lores, with several of these appearing strikingly pale-lored and "open-faced" (strongly recalling both Isabelline and female Red-backed Shrikes). In trying to allow for this it may be possible that this bird is a female phoenicuroides, with earth-brown upper-parts, a (for a female) fairly prominent supercilium and white under-parts. Bill is short, heavy, and hooked. Underpart Barring Many such individuals cannot yet be safely ascribed to subspecies; and more surprisingly it appears that a very much smaller number perhaps cannot even safely be ascribed to species in field conditions. Some seem to show a rather weak supercilium, while others perhaps tend to appear closer to superciliosus, with extensive white in the supercilium, extending to the forehead. adults in winter (e.g. Vol. No Brown Shrike of any subspecies, sex or age it is said (though see below) should show extensive white at the base of the primaries (to quote from Svensson [1992]: "bases to primaries only very rarely with some white [only 0-2 mm longer than the primary coverts if any]". Both sexes (especially in spring) appear obviously dark and cold-toned brown in the upperparts, with strikingly clean pale fringes to the tertials (often more marked on the outer edge), and a more warmly-colored rump and base to the tail (often darkening distally). 45 (1): 1-235. The distinction is not easy to use in the field but has been tested with breeding birds in Japan where the female can be identified from the presence … Near the entrance to the preserve (at an elev. “Unfortunately, like any good predator, it did not turn its back to m e, so images of the wings, tail or back. Female have fine scalloping on the underside. Concerning confusus, the literature is rather poor in describing its appearance and it appears to be used either to describe a subspecies in its own right or as a term to cover the extreme variety of intergrades between lucionensis and cristatus (and/or superciliosus). Identification Guide to European Passerines, 4th Edition. their already dark lores, and largely uniform reddish-brown upperparts (lacking any grey tones on the nape or mantle, and e.g. Company number 09846917 registered in England & Wales. Bills of full adults are invariably black or blackish, while presumed second calendar year birds also occasionally show slightly paler bills basally. Based on the combination of these features, such individuals can easily be ascribed to the Japan- and Sakhalin-nesting superciliosus. 4. Stockholm. These quite possibly represent an intergrade or hybrids between lucionensis and the "reddish-backed" subspecies (i.e. Allowing for the great variability in both Isabelline and Brown Shrike, reference to Svensson (1992), Svensson et al (1999), and Worfolk (2000) suggest that the vast majority of adults should still be safely separable on the basis of the following main criteria: Three out of four subspecies of Brown Shrike show reddish or reddish-brown upperparts and strongly yellow-buff ventrally and on the flanks, while all subspecies of Isabelline Shrike except phoenicuroides show sandier or grayer tones to the upperparts. The underside is creamy with rufous flanks and belly. Svensson, L. & P. Grant. At the gate, I found Asian Brown Flycatcher Muscicapa latirostris latirostris and Oriental Magpie-Robin Copsychus saularis prosthopellus. A perhaps lesser number (including one "sandy-backed" type in 2004), show rather weaker vestigial type patches. While very similar to "reddish-backed" subspecies in structure and behaviour, most lucionensis nonetheless seem rather more approachable and prone to perching in the open, and in addition most appear to show a rather square-cut tail, seeming to lack the slight gradation shown by many, but not all, "reddish-backed" birds. The vast majority of adult, and even second calendar year Brown Shrike females of all subspecies are believed to show either dark brown or blackish lores. In addition, hybridisation between the various subspecies is not well-studied, but it seems, based on the extreme variability of many individuals seen in South Korea and elsewhere, that it might well be rather extensive. Occasional individuals seen in Korea that appear to show mixed characteristics of superciliosus and perhaps confusus or lucionensis (i.e. Confusus, Female, Bakryeong Island, May 20 2015 © Nial Moores. Most of the underparts are typically saturated with warm yellow-buff, tinged more strongly apricot on the flanks. Young: Both parents feed nestlings. It's conceivable that the odd female or juvenile does get quite dark, like the Scillies bird last year, which had a typical Red-backed Shrike wing-formula (see here - you'll need to login to surfbirds though - browner than ours though). Give attention to being clearer about what is needed. This shows a really quite dull and dark bird almost lacking any rufous tone at all – I suspect it has a cyan colour cast. Many also show fairly apparent growth bars and also slightly paler buffy-tips to at least the 5th and 6th pairs of tail feathers (as described by Svensson, 1992). Young leave the nest about 19-20 days after hatching, are tended by parents for several more weeks. A very few individuals (less than 1%, and these perhaps intergrades) show some white at the base of the primaries. Eggs pale gray or greenish white, spotted with brown, olive, and gray. This includes lucionensis types with much brown admixed into the crown (considered by Worfolk [2000] to be better described as the intergrade confusus).

Save my name, e-mail, and website in this browser for the next time I comment. Male has an ash-gray head, an inky black mask, white underparts, and scaly chestnut wings. Brown Dove — Represents a subconscious thought that is less than clear. A large tit flock near the pool contained only a female Blackcap and a few Goldcrests of note. It was prompted by noting differences between Brown Shrike seen in the field and descriptions of the species contained in available literature, and by subsequent discussion over the possible difficulty of some individual’s separation from Isabelline Shrike L. isabellinus (with lesser attention given to Red-backed Shrike L. collurio, a species first recorded in South Korea in September 2004. While highly distinctive in "typical" plumages at the extreme ends of each subspecies (i.e. It is commonly known as the "butcherbird" or "thorn bird" for its habit of impaling prey on sharp objects, such as thorns and barbed wire fences. Tail is long and round-tipped with faint bars. the majority, based on Worfolk’s descriptions) appear, in Korea at least, to be intermediate in appearance. Their frequency suggests strongly that they are not all vagrant Isabelline. Brown Shrike: Small shrike with warm brown upperparts and buff underparts. Despite its small stature, the behaviors of a shrike reflect those of a raptor. In addition there is suggestion of hybridisation between the various subspecies. After a while, a second bird turned up. Robson, C. (2000). “The Green Imperial Pigeon (Ducula aenea) is listed as a rare non-breeding visitor in Singapore....

The Brown Shrike is a highly variable species. Confident identification of some individuals is even further complicated by hybridization between Isabelline and both Red-backed L. collurio and Brown Shrike in Central Asia at least (e.g. (1999). Here they are brown supporting a first year bird, but this can also be seen in some adult females (see: LINK). New Holland publication. Females have some variable amounts of vermiculations on the underparts. Like other shrike it has black “Bandit-mask” though the eye. The note concludes that significant further research needs to be conducted before identification criteria (or even taxonomic decisions) can be fully determined for the Brown Shrike taxa, and by extension Isabelline Shrike taxa, and that extreme caution needs to be used when identifying "atypical" extralimital shrikes of either species. The supercilium is often rather poorly marked and suffused with grey, though sometimes it can be more prominent and whitish. Lores At first we only noted one bird, a female Brown Shrike (Lanius cristatus) feeding close to the fence. Males of both subspecies lack vermiculations (according to Svensson, 1992), while females tend to show variable but weak brown vermiculations or barring especially on the flank and breast sides, and juveniles extensive vermiculations below and above. Brown Shrike. 21: Female Brown Shrike, South Korea, May.
