It may relocate if the hunting success drops off or if it is disturbed by a passerby. These birds also build nests of mud and twigs but need a slight ledge to set it upon. Another of my favorites is the Killdeer. These sharply marked shore birds glean for bugs and spiders at the water's edge but are also at home on large areas of turf. They make full use of football fields during the hot summer months when the kids are away.
Flood irrigation floats up a bonanza of insect prey on a regular basis.
Along the fences and side canal banks are two kinds of trees that often volunteer. One is the Mesquite. It has dark deeply furrowed bark and feathery compound leaves. Where branckes have been broken or cut mesquites often ooze a black gooey sap. Spikes of yellow flowers come in April and there are mesquite bean pods by June.
