Abstract Artificial nesting islands, or rafts, are often deployed in common loon (Gavia immer) breeding territories to decrease negative impacts of mammalian predation and water-level fluctuations on nesting success. The management value of rafts has been demonstrated in other studies; however, no published studies have quantified the use or associated reproductive benefits of rafts on lakes exhibiting water-level fluctuations. These lakes constitute a major portion of loon nesting habitat in… Expand
Effects of water-level management on nesting success of common loons
Water-level management is widespread and illustrates how contemporary climate can interact directly and indirectly with numerous biological and abiotic factors to influence reproductive success ofExpand
Guidelines for Constructing and Deploying Common Loon Nesting Rafts
The raft construction and deployment protocol currently followed by organizations specializing in loon management and research in New Hampshire and Maine is presented, and emerging concerns related to management using rafts are discussed. Expand
Common Loon (Gavia immer) Nesting Habitat Models for North-Central Minnesota Lakes
Abstract. Shoreline attributes and extensive field surveys of aquatic vegetation and animal presence were used to determine probabilities of Common Loon (Gavia immer) nesting for segments ofExpand
Nest platforms increase aggressive behavior in common loons
This study is one of a few to show that tools used to mitigate habitat loss can negatively impact reproductive fitness in a threatened species. Expand
The Red-throated Diver (Gavia stellata) in human-disturbed habitats - building up a local population with the aid of artificial rafts
Human actions, such as increasing recreational activity at lakes, have resulted in a deterioration in the quality of diver breeding grounds. We studied the breeding success of Redthroated DiversExpand
Landscape Assessment of Habitat and Population Recovery of Common Loons (Gavia immer) in Massachusetts, USA
Results indicated that a large-scale recovery may be possible as enough suitable habitat exists to support about 300 pairs statewide, and management efforts can be increased to encourage further growth. Expand
Modeling Habitat Associations for the Common Loon ( Gavia immer ) at Multiple Scales in Northeastern North America
It is suggested that the Common Loon responds to both ecological and anthropogenic factors at multiple scales when selecting breeding sites, and ecoregional multiscale models can be used to identify and prioritize the conservation of preferred nesting habitat for Common Loons populations. Expand
Juvenile survival in common loons Gavia immer: effects of natal lake size and pH
Estimating juvenile survival and its predictors in a population of common loons Gavia immer and investigating predictors of chick mass, survival and inter-sibling size disparity in two-chick broods suggests that loon populations are healthier than often supposed. Expand
Effects of Spatial Disturbance on Common Loon Nest Site Selection and Territory Success
ABSTRACT The common loon (Gavia immer) breeds during the summer on northern lakes and water bodies that are also often desirable areas for aquatic recreation and human habitation. In northern NewExpand
Physical, human disturbance, and regional social factors influencing Common Loon occupancy and reproductive success
ABSTRACT Common Loons (Gavia immer) appear to use physical habitat, human disturbance, and social cues when selecting territories; however, recent loon habitat models suggest that the importance ofExpand


Responses of breeding common loons to human activity in upper Michigan
Breeding populations of the common loon (Gavia immer) in Michigan have declined in the past several decades, resulting in classification of this species as threatened under state law. FactorsExpand
Responses of breeding common loons to human activity in Upper Michigan
Higher levels of human activity did not affect production of chicks by loons under the conditions observed, but these results should not be extrapolated to lakes experiencing much higher human use. Expand
Breeding success of raft-nesting divers in Scotland
A study in 1972-78 showed that Red-throated Gavia stellata and Black-throated Divers G arctica nesting in an area of south Argyll, Scotland, where there was a shortage of island nest sites, sufferedExpand
Floating platforms increase reproductive success of common loons
In a controlled experiment, the efficacy of using floating nest platforms to increase reproductive success of loons and thus help sustain local populations was examined. Expand
Breeding patterns of Common Loons on lakes with three different fish assemblages in north-central Alberta
The occurrence and breeding patterns of Common Loons were influenced by prey assemblage and habitat type, but nesting loons and fledglings were more likely to be present on pike lakes than on fishless or minnow lakes. Expand
Local movements of color-marked common loons
Regular use by loons of small clusters of lakes suggests that a management strategy that preserves only small, isolated breeding lakes might be inadequate to sustain nesting pairs and also might hamper natural dispersal between lakes. Expand
The impact of cottage development on common loon reproductive success in central Ontario
The purpose of the study was to investigate the impact of cottage development on the reproductive success of Common Loons in central Ontario and found that extensive water-oriented recreation may be detrimental to loon productivity. Expand
Common loon reproduction and chick feeding on acidified lakes in the Adirondack Park, New York
No chick mortality could be attributed to lake acidification, but chicks on low-pH lakes were generally fed prey much smaller or much larger than those normally preferred, and a pair nesting on a fishless lake fed aquatic insects to their constantly begging chick, spending two to four times longer feeding the chick compared with loons on lakes with fish.

Ducks nesting in association with gulls—an ecological trap?
The reproductive success of ducks nesting in association with gulls on islands in Miquelon Lake, Alberta, was studied and duckling mortality, concentrated in the 1st week posthatching, was positively correlated with the numbers of associated gulls. Expand
Effects of Lake Characteristics and Human Disturbance on the Presence of Piscivorous Birds in Northern Wisconsin, USA
Abstract Despite current anthropogenic alterations to riparian areas and littoral zones of lakes, little information is available on how human-induced alterations affect lacustrine habitat use byExpand
