“…There is growing evidence that pesticides and other toxicants disrupt flight efficiency and navigation in birds. Homing pigeons ( Columba livia ) exposed to carbamate (carbofuran, aldicarb) and organophosphate (chlorpyrifos) insecticides took significantly longer to return to their home loft after release 24 , 25 . There is also evidence that disruption of flight orientation is a sensitive endpoint of contaminant exposure in birds.…”

Birds that travel long distances between their wintering and breeding grounds may be particularly susceptible to neurotoxic insecticides, but the influence of insecticides on migration ability is poorly understood. Following acute exposure to two widely used agricultural insecticides, imidacloprid (neonicotinoid) and chlorpyrifos (organophosphate), we compared effects on body mass, migratory activity and orientation in a seed-eating bird, the white-crowned sparrow (Zonotrichia leucophrys). During spring migration, sparrows were captured, held and dosed by gavage daily for 3 days with either the vehicle control, low (10% LD50) or high (25% LD50) doses of imidacloprid or chlorpyrifos and tested in migratory orientation trials pre-exposure, post-exposure and during recovery. Control birds maintained body mass and a seasonally appropriate northward orientation throughout the experiment. Imidacloprid dosed birds exhibited significant declines in fat stores and body mass (mean loss: −17% low, −25% high dose) and failed to orient correctly. Chlorpyrifos had no overt effects on mass but significantly impaired orientation. These results suggest that wild songbirds consuming the equivalent of just four imidacloprid-treated canola seeds or eight chlorpyrifos granules per day over 3 days could suffer impaired condition, migration delays and improper migratory direction, which could lead to increased risk of mortality or lost breeding opportunity.

“…It is widely used for the control of soil dwelling and foliar feeding insects including wireworms, white grubs, weevils, stem borers, aphids, and several other insects [4]. Carbofuran is known to be more persistent than other carbamate or organophosphate insecticides [5]. Carbofuran is degraded in water by hydrolysis, microbial decomposition, and photolysis.…”

The adsorption of insecticide, carbofuran from aqueous solution onto activated carbon derived from palm oil fronds (PFAC) was investigated through batch study. The effects of both initial concentration and pH of the carbofuran over the range of 25 to 250 mg/L and 2 to 12, respectively, on the adsorption of the prepared PFAC were studied in batch experiments. Equilibrium data were fitted to the Langmuir, the Freundlich, and the Temkin isotherm models. The results obtained from application of these models show that the best fits were achieved with the Langmuir model, and a maximum monolayer adsorption capacity of 164 mg/g was obtained at 30°C. The regeneration efficiency of spent activated carbon was studied and it was found to be 90.0–96.4%. The results indicated that PFAC has good capability as adsorbent for the removal of carbofuran from aqueous solutions.

“…Furthermore, some of the magnetic responses were wavelength dependent, a fact supporting the chemical hypothesis of magnetoreception. Thus, it is not surprising that this study has been steadily cited in several studies as proof of the existence of magneto-sensitive units in the avian brain (Able 1994 ; Azanza and Del Moral 1994 ; Ahmad et al 2007 ; Brasel et al 2007 ; Burger et al 2010 ; Buttemer and Chappell 2010 ; Bischof et al 2011 ; Begall et al 2013 ; Beason 2005 ; Beason et al 1995 , 1997 ; Bingman et al 1988 ; Cain et al 2005 ; Deutschlander et al 1999 ; Edmonds 1992 , 1993 , 1996 ; Finney 1995 ; Fischer et al 2001 ; Johnsen and Lohmann 2005 ; Jorge and Vicente 2006 ; Keary and Bischof 2012 ; Kobayashi and Kirschvink 1995 ; Leucht 1990 ; Liboff and Jenrow 2000 ; Lohmann and Lohmann 1993 ; Lohmann and Johnsen 2000 ; Mai and Semm 1990 ; McKay and Persinger 2005 ; Mehlhorn and Rehkamper 2009 ; Mouritsen et al 2004 ; Muheim et al 2002 ; Munro et al 1997 ; Nemec et al 2001 , 2005 ; Niessner et al 2011 ; Olcese and Hurlbut 1989 ; Olcese et al 1988a , b ; Partch and Sancar 2005 ; Phillips 1996 ; Phillips and Borland 1992a , b ; Phillips and Borland 1994 ; Phillips et al 2010 ; Phillips and Sayeed 1993 ; Picazo et al 1993 ; Ritz et al 2000 , 2002 ; Rowe 1999 ; Schneider 1995 ; Semm and Beason 1990b ; Shcherbakov and Winklhofer 1999 ; Stehle et al 1988 ; Taube 1998 ; Thoss and Bartsch...…”

Extracellular recordings reveal absence of magneto sensitive units in the avian optic tectum

There is a consensus that birds detect the earth’s magnetic field and use some of its features for orientation and homing purposes. Since the late 1960s, when the first solid behavioral evidence of magnetoreception was obtained, much research has been devoted to describing the ethological aspects of this behavior. The neurophysiological basis of magnetoreception has been much less studied, although a frequently cited 1986 report described a high prevalence (70 %) of magneto-sensitive neurons in the pigeon optic tectum with high signal-to-noise ratios (Semm and Demaine, J Comp Physiol A 159:619–625, 1986). Here, we repeated these neurophysiological experiments using anesthetized as well as awake pigeons and new recording techniques. Our data indicate that magneto-sensitive units do not exist in the avian tectum.
