Pine Siskin Dead Bird Update

Pine siskin, a small bird, perched on a branch

In early February, the Wildlife Investigations lab within California Department of Fish and Wildlife (CDFW) confirmed the suspected Salmonella outbreak among pine siskins. CDFW received more than 1,200 dead bird reports within the month of January alone. The Bay Area is a hotspot for the bacteria simply because there is a high concentration of birdfeeders. The District began to receive reports of dead pine siskins and finches in late December 2020. Since that initial report, about half of the total dead birds tested by the San Mateo District Laboratory have been pine siskins (23/42). District staff continues to encourage residents to suspend the use of bird feeders in their yard at this time.

Laboratory Receives Reports of Dead Pine Siskins

It seems as if 2020 needed to squeeze in a bit more bad news as the year comes to an end. The District as well as the California Department of Public Health (CDPH) have observed a high number of dead bird calls describing a sparrow-like bird.  SMCMVCD laboratory staff have identified these birds to be Pine Siskins (Spinus pinus), which can often be confused for other finches or even American sparrows. Pine siskins are fairly small with yellow patches on the wings and a short, forked tail.

It’s Termite Season

If you take walks in the early morning or evening you may have recently seen clouds of fluttering insects rising from the ground. They don’t fly well, but when backlit by the sun, it makes you think of quiet days sitting by a lake in the morning mist.

If only they weren’t termites.

New Larviciding Methods at Mills Field

In September and October, the district was having trouble penetrating vegetation with a granular larvicide in Mills Field (San Bruno) that was breeding mosquitoes. Staff decided to set up a sprayer that would put out a high volume of liquid larvicide that would push through the cattails and into the water. Mills Field is usually a helicopter treatment site with 32 acres of mosquito breeding habitat. This year, most of the water had dried up, leaving a 5-acre ditch which did not warrant the cost of a helicopter treatment.

A Short History of Malaria in California

Many people may not know that there was a time, not long ago, when malaria was more than a disease you only worried about when traveling. Malaria is a mosquito-borne disease resulting from a parasite that causes fever, chills and flu-like symptoms that can progress to liver and kidney failure, or even coma and death in the worst cases. There are four protozoa that can cause the disease: Plasmodium falciparum, P. malariae, P. ovale and P. vivax.  All four of these parasites are carried by mosquitoes in the genus Anopheles.
