Today's Mystery Bird For You To Identify I'm not sure whether most of you can identify this species, but there are a couple clues in this image that should prove helpful for those who know what to look forMystery Bird photographed at the 14th annual hawk watch at Smith Point, Gulf Coast Bird Observatory, Chambers County, Texas, USA. [I will identify this bird for you in 48 hours]Image: Joseph Kennedy, 30 September 2010 [with binoculars].Nikon D200, Kowa 883 telescope with TSN-PZ camera eyepiece 1/750s f/8.0 at 1000.0mm iso400I'm not sure whether most of you can identify this species, but there are a couple clues in this image that should prove helpful for those who know what to look for -- and yes, you are invited to "blurt out" this species' ID whether you are a beginner or an expert (but you must say which field marks you used to settle upon your identification). Daily Mystery Bird Rules: 1. Please name at least one field mark that supports your identification, keeping in mind that more than one field mark is often necessary to distinguish between species. IDs without any supporting information are not valid and may be deleted by the moderators. 2. Expert and intermediate level birders: do NOT try to be the first to blurt out the mystery bird's ID. Instead, please provide helpful hints, such as descriptions, literary references, puns, personal anecdotes, and other forms of discussion and assistance for beginning birders and for those following on their iPhones without naming the species. Expert and intermediate birders are free to name the bird species 24 or more hours after it was first published.3. Each mystery bird is usually accompanied by a question or two. These questions can be useful for identifying the pictured species, but may instead be used to illustrate an interesting aspect of avian biology, behaviour or evolution, or may be intended to generate conversation on other topics, such as conservation. 4. Each bird species will be demystified 48 hours after publication. If you have bird images, video or mp3 files that you'd like to share with a large and appreciate audience, feel free to email them to me for consideration.GrrlScientistguardian.co.uk © Guardian News & Media Limited 2010 | Use of this content is subject to our Terms & Conditions | More Feeds guardian.co.uk |
