Notes:
(1) Bus 78 from Harvard Square, Blanchard Road becomes Brighton St. in Belmont, crosses railroad tracks; get off opposite Hoitt Rd. (on left) and between the 2nd part of Sandrick Rd. loop and Larch Circle (on the right). Find public access lot leading to a stone wall at the edge of the pond.
(2) Alewife eggs when fertilized are translucent and about 1 mm in diameter. Blueback herring eggs are similar but can be adhesive to the substrate. Both eggs settle to the bottom. Care should be taken when walking around areas with high densities of eggs deposited. When the eggs die they turn white and can easily be seen on the bottom.
(3) Look up these in a fish book
(4) Look these up in bird book, see also Great Black-backed Gull
