This form is intended as a convenience in reporting observations of species on the Louisiana Bird Records Committee (LBRC) Review List. The LBRC recommends the use of this form or a similar format when submitting records for review (to assure that all pertinent information is accounted for). Attach additional pages as necessary. Please print or type. Attach xerox of field notes, drawings, photographs, or tape recordings, if available. Include all photos for more obscurely marked species. When completed, mail to Secretary, Louisiana Bird Records Committee, c/o Museum of Natural Science, 119 Foster Hall, Louisiana State University, Baton Rouge, LA 70803-3216.

1. English and Scientific names: Ferruginous Hawk (Buteo regalis)

2. Number of individuals, sexes, ages, general plumage (e.g., 2 in alternate plumage): One in first basic plumage

3. Locality: LOUISIANA: Cameron

Specific Locality: Willow Island off Lebleu Camp Rd., ca. 5.0 mi. E of Cameron

4. Date(s) when observed: 30 January 2013

5. Time(s) of day when observed: 12:45 PM CST

6. Reporting observer and address: Justin Bosler
                                                        Lancaster, PA / Port Clinton, OH

7. Other observers accompanying reporter who also identified the bird(s): Devin Bosler

8. Other observers who independently identified the bird(s): none

9. Light conditions (position of bird in relation to shade and to direction and amount of light): Initially somewhat backlit against the sky to the east, then passed directly overhead providing both observers excellent close range visual in ideal light.

10. Optical equipment (type, power, condition): Zeiss Conquest HD 8x42 (new), Canon EOS 40D DSLR w/ 200-500 mm Tamron telephoto lens (good)

11. Distance to bird(s): within 25 meters at closest point.

12. Duration of observation: only about a minute.

13. Habitat: Heavily disturbed and degraded coastal chenier ridge dominated by hackberry-baccharis-acacia scrub, with scattered yucca-prickly pear thickets surrounded by unimproved pasture and coastal marsh.

14. Behavior of bird / circumstances of observation (flying, feeding, resting; include and stress habits used in identification; relate events surrounding observation): The hawk was more or less in a low, direct flight from east to west along the marsh-pasture interface. It appeared to be loosely associated with and commuting (locally, I presume, given the date of occurrence) with a small group of Red-tailed Hawks also moving along this same flight path into a very strong headwind (gusty WNW winds to 40+ mph).

15. Description (include only what was actually seen, not what "should" have been seen; include if possible: total length/relative size compared to other familiar species, body bulk, shape, proportions, bill, eye, leg, and plumage characteristics. Stress features that separate it from similar species): Large, pale Buteo with light gray-brown upperparts and largely unmarked underparts. The wings were long, broad and rather pointed. The underwing coverts were lightly marked, including the patagials.  Contrasting with the largely unmarked ventral surface were dark carpal or “wrist” patches. The primaries and secondaries showed faint, diffuse barring.  Dorsally, it appeared very Krider’s Hawk-like with the conspicuous whitish panels on the inner primaries. The tail was a seemingly unmarked ground color with faint subterminal band. It showed a pale head with whitish supercilium and dark postocular. Quite conspicuous at close range was the extended yellow gape which. More apparent in photographs than in the field were light buffy leggings.  Overall pale aspect, yellow irides, and lack of solid subterminal band on remiges indicative of a juvenile.

16. Voice: none heard.

17. Similar species (include how they were eliminated by your observation): Krider’s Red-tailed Hawk eliminated by lack of dark patagials, long, tapered wings, sparsely marked underwing coverts and underparts, dark carpal crescents, extended gape, combination of prominent supercilium and dark postocular mark, and feathered tarsi.

18. Photographs or tape recordings obtained? (by whom? attached?): Yes, photographs obtained by myself and attached.

19. Previous experience with this species: A fair amont of experience with both immature and adult light morph Ferruginous Hawks throughout their typical range in the West, east to s. TX.

20. Identification aids: (list books, illustrations, other birders, etc. used in identification):

a. at time of observation: none

b. after observation: none
