They noted that there were “seven Farallones close together.” Though the Spanish captains knew of the Farallones it was believed that they never set foot there. The following 200 years left the islands relatively untouched. It was not until the proliferation of fur traders that degradation of the islands began. Fur seals are medium-sized marine mammals, with males growing up to 600 pounds and females topping out at 110 pounds. Fur seals became highly coveted for their warm, dense fur, which has 300,000 hairs per square inch.

  • Brief Description of Project
    Detailed Background on Existing Resource Conditions in Project/Study Area Giacomini Wetland Restoration Project Golden Gate National Recreation Area/ Point Reyes National Seashore Land Use: The Giacomini Ranch has been used for dairy farming since 1917. The Giacominis established their operation in the 1940s with diking of what is now referred to as the East and West Pastures and are still farming the ranch currently. The National Park Service’s reservation of use agreement with the Giacominis ends in 2007 at which the dairy operation will cease, and the entire 563 acres will be under the National Park Service (Park Service) ownership and management. Olema Marsh, which is directly south of the Giacomini Ranch in the Olema Valley, has been owned by the non-profit organization, Audubon Canyon Ranch. The marsh is primarily used by the public for walking, birding, and sightseeing opportunities. The West Marin area, including Point Reyes National Seashore (Seashore) and north district of Golden Gate National Recreation Area (GGNRA), is largely rural and comprised of agricultural operations and small residential communities. The dominant type of agriculture within the region is dairy and beef cattle operations. South of Olema Marsh lies pasturelands that are owned by the Park Service and grazed under lease by beef cattle. Leased beef cattle grazing also occurs near Park Service land at Railroad Point northeast of the Giacomini Ranch. Otherwise, most of the Giacomini Ranch and Olema Marsh is surrounded by the towns of Point Reyes Station and Inverness Park, which consist largely of residential homes and small businesses. To the north of Giacomini Ranch lies undiked marshlands that are owned by the State Lands Commission.

  • American Avocet Breeding Habitat, Behaviour and Use of Nesting Platforms at Kelowna, British Columbia
    Avocet breeding habitat, behaviour, and nesting platform use ­ Gyug and Weir 13 American Avocet breeding habitat, behaviour and use of nesting platforms at Kelowna, British Columbia Les W. Gyug1 and Jason T. Weir2 1 Okanagan Wildlife Consulting, 3130 Ensign Way, West Kelowna, BC V4T 1T9 [email protected] 2 Dept. of Biological Sciences and Dept. of Ecology and Evolution, University of Toronto, 1265 Military Trail, Toronto, ON M1C 1A4 [email protected] Abstract: The largest and most consistently used American Avocet (Recurvirostra americana) colony in British Columbia is located in the southern half of the former Alki Lake, Kelowna. This lake was a landfill active from the 1960’s to 1980’s, and is now slated to be filled in completely as the landfill re­expands into the remnants of the lake. Here, we report avocet behaviour, nest conditions and foraging habitat characteristics in 1999 at Alki Lake and five other wetlands in the Kelowna area to inform future mitigation strategies for this colony. Thirteen breeding pairs initiated 21 nests (including renesting after failed attempts) at Alki Lake in 1999, with no nests in other Kelowna area localities. Fifteen nests were on islands, five on 1.2­ m square floating nest platforms, and one on a shoreline mudflat. Nesting on floating nest platforms had not been previously reported for American Avocets. Foraging areas regularly used by individual pairs were not necessarily adjacent to the nest, and increased from 0.32 ha during the incubation period to 0.53 ha after hatching. Avocets foraged primarily in soft silt substrates along non­vegetated shorelines and in shallow mudflats at a mean depth of 10 cm.

  • Hatching Success in Avocet Recurvirostra Avosetta and Black-Winged Stilt Himantopus Himantopus
    Bird Study (2005) 52, 166–172 Hatching success in Avocet Recurvirostra avosetta and Black-winged Stilt Himantopus himantopus JOSÉ JAVIER CUERVO Estación Experimental de Zonas Áridas, Consejo Superior de Investigaciones Científicas, Calle General Segura 1, E-04001 Almería, Spain Capsule Daily survival rate of nests was influenced by laying date and nesting period (laying versus incubation) in both species and by colony size in Black-winged Stilts. Aims To investigate the effect of clutch size, colony size, reproductive phenology and nesting period on hatching success of Avocets and Black-winged Stilts. Methods The study was undertaken at two localities in southwestern Spain (Doñana and Odiel Natural Parks) during 1990 and 1991 breeding seasons. The Mayfield method was used to estimate hatching success. Results Both species bred colonially and some colonies included nests of both species. Neither year, locality, species or clutch size had a significant effect on hatching success. Daily survival rate was lower for late nests than for early and intermediate, and lower during egg-laying than during incubation in both species. Hatching success of Black-winged Stilt nests was lower in large colonies (>50 nests) than in medium-sized ones (11–50 nests). Conclusion Late clutches within a colony (clutches with the least hatching success) might be replacements or belong to late breeders, but adults were not individually marked, precluding clarification. The results suggest a high probability of clutch predation and/or desertion in early stages of the nesting period, especially shortly after laying the first egg. The fact that hatching success in large colonies was lower than in medium-sized ones, but only for Black-winged Stilts (not for Avocets), might help to explain the difference in coloniality of the two species.

V4T 1T9 [email protected] 2 Dept. of Biological Sciences and Dept. of Ecology and Evolution, University of Toronto, 1265 Military Trail, Toronto, ON M1C 1A4 [email protected] Abstract: The American Avocet (Recurvirostra americana) is a rare and localized breeder in British Columbia with the single largest known B.C. colony in the remnant southern half of Alki Lake in Kelowna. From 1997–2015, up to 27 nests with eggs were observed in a single year, although in some years there appeared to be no successful nesting. Pulses in spring of high numbers of avocets at Alki and Robert lakes in Kelowna appeared to be partly from avocets heading further north in B.C. on their spring migration. High numbers of avocets only appear to remain in Kelowna for the breeding season if water levels in Alki Lake are suitable to isolate nesting islands. Spring first arrival dates of avocets to Kelowna have become significantly earlier by, on average, 11 days from 1997–2015. Egg laying dates in 1999–2000 ranged between April 25 and June 22, while hatching dates ranged between May 29 and July 20. Mean clutch size from 1997–2001 was 3.97 eggs per clutch. Nesting success in terms of broods hatching was 33% in 1999 and 60% in 2000.
