brown shrike female
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. The Brown Shrike, of the subspecies lucionensis, was considered by Tomek (2002) to be a "common breeding species throughout" DPRK (though she notes that Fiebig suggested that the coloring of all birds he saw was typical of confusus). 3. “Unfortunately, like any good predator, it did not turn its back to m e, so images of the wings, tail or back. “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 Collins Bird Guide. The supercilium in first year birds is said to run only from the anterior eye level (see Wells 2007). 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. Laughing Dove — Sacred to the goddess Venus, the Queen of Laughter. This note agrees that more research is required, and basing an opinion on the difficulties of identifying many individuals to subspecies in the field, follows the more conservative Svensson (1992) and Robson (2000) in treating Brown Shrike as a single species, with four subspecies (the clearly diagnosable nominate cristatus, lucionensis, superciliosus and the somewhat enigmatic and poorly-described confusus). "sandy-backed" individuals of unclear provenance (perhaps also largely attributable to confusus?). The ear coverts are black in most adults. 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. The Bill 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. However, there are no mid-winter records of lucionensis known to Birds Korea, with the latest records traced being two old specimens in the DPRK said, perhaps in error, to have been collected in November (reported in Tomek, 2002). 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. These quite possibly represent an intergrade or hybrids between lucionensis and the "reddish-backed" subspecies (i.e. Vol. © 2020 Bird Ecology Study Group - WordPress Theme by Kadence Themes, 2005-2019: Fifteen years of postings on bird behaviour will have to come to an end, Seed Pellet Regurgitation by the Endemic Black Currawongs of Tasmania, Sleeping behaviour of the Common Tailorbird, Female Indian Peafowl Prejudiced Against Albino Offspring, Sightings of engraved colour flags on shorebirds, Tanimbar Corella and Yellow-crested Cockatoo, Olive-backed Sunbird : A miscalculated nesting. The remainder are comprised largely of either cristatus or confusus, "reddish-brown backed" types. Range and Habitat However in this bird it is clearly outlined from the base of the beak to the back of the eye. The remainder of reddish-backed individuals are more difficult to ascribe to subspecies, and show great variation. While highly distinctive in "typical" plumages at the extreme ends of each subspecies (i.e. In the park I stopped at a parking area at elev.

Adults usually have dark black, well developed lores. Bills of full adults are invariably black or blackish, while presumed second calendar year birds also occasionally show slightly paler bills basally. The disputed type confusus occurs in the south-eastern part of this range (in the Amur and Ussuri basins) and is the type recorded breeding in Heilongjiang and far north-eastern Inner Mongolia, China (also possibly in North Korea: Fiebig per Tomek, 2002). Adult lucionensis is the most distinctive and arguably the most attractive-looking of the subspecies of Brown Shrike occurring in South Korea, appearing rather distinct from Isabelline Shrike. 800 pp. Nial Moores Although most Brown Shrike females are dark-lored, very occasional individuals show largely pale 330 x 286px 79.59KB Female have fine scalloping on the underside. This bird has significant barring of the breast sides and flanks supporting a first year bird. 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!". Clutch size varies, often 4-7 eggs, up to 9 in Alaska. Females tend to have fine scalloping on the underside and the mask is dark brown and not as well marked as in the male. The underside is creamy with rufous flanks and belly. the majority, based on Worfolk’s descriptions) appear, in Korea at least, to be intermediate in appearance. The underside is creamy with rufous flanks and belly. Based on a series of images (taken in May and September 2003 and especially in May 2004), this note. 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). 27th September 2018, Location: Ipoh, Perak, Malaysia As I... “This female Asian Paradise-flycatcher (Terpsiphone paradisi) surprised me by coming alongside me at a stream... “On 23rd Aug 15, a young friend named Caleb, stopped me and pointed...

The greatest concentrations of Brown Shrike, of all three or four subspecies, are therefore of migrants on offshore islands from late April to early June and again, in rather smaller numbers, in August and September, with occasional individuals into October. Tail is long and round-tipped with faint bars. Worfolk, 2000), or as three subspecies with complete gradation between populations (Svensson, 2003), the latter noting that: "It’s not only that 75% of the females and even more juveniles are indistinguishable, many males show a frustrating mix of characters". The committee agreed by consensus that this bird was a female brown shrike, although they are still investigating hybrid possibilities. Many adult Isabelline (with the exception of "western" phoenicuroides) show obviously paler bills basally than Brown Shrike. II, Passerines. adults in winter (e.g. Image by: 1) Imran_Shah - Pakistan 2) SJ Ahanmi - United Arab Emirates 3) Pkspks - India 4) Ali Al-Mohannadi Females appear rather similar to males, though perhaps look a little colder-brown, and some seem to show rather more brown admixed into the crown (though this could also perhaps reflect intergradation with other subspecies: if so more than 50% of all later-migrating lucionensis in spring in South Korea show some such intergradation). After a while, a second bird turned up. With the exception perhaps of isabellinus most Isabelline also have rather less saturated coloration on the underparts than most Brown. Occasional individuals seen in Korea that appear to show mixed characteristics of superciliosus and perhaps confusus or lucionensis (i.e. I have many more images of the front if there is any request. Brown Dove — Represents a subconscious thought that is less than clear. Confusus, Female, Bakryeong Island, May 20 2015 © Nial Moores. One such individual in early June also showed a largely pinky-grey base to the bill. 45 (1): 1-235. Robson, C. (2000). As might be expected, in spring the majority of earlier-migrating individuals tend to be males, followed by females and finally second calendar year birds, though there appears to be significant overlap, as also might be expected considering the asynchronous migration strategies of the various subspecies and the presumed wide geographical area over which such birds might be breeding.
