Dickcissel

Spiza americana

Length: 6.5 inches Wingspan: 10 inches Seasonality: Summer
ID Keys: Male distinctive with black bib, yellow chest, white chin, and yellow eyebrow. Females lack black bib.

Dickcissel - Spiza americanaDickcissels are a vocal summer resident in the state, especially in the eastern part, where they can often be found singing their distinctive song  from fenceposts, wires, and plant tops.  With their yellow chest and black "bib", they share a general resemblance to the much larger Meadowlark.  They seem to vary locally quite a bit from year to year, presumably in response to vegetation condition and other habitat parameters.  Several birds may utilize the same field or grassy area during the summer breeding season, but the most frequent sighting of a Dickcissel in South Dakota is of a single bird (often a vocalizing male). However, during the winter months, Dickcissels may form massive flocks numbering in the thousands.

Habitat: Nests in alfalfa and clover fields, as well as native meadows and grasslands.  

Diet: Primarily insects in the summer, particularly for young birds, or adult females feeding young.  Seeds and grains may make up the majority of the winter diet.

Behavior: Uses a variety of foraging techniques dependent upon season and location. Insects may be gleaned from vegetation or plucked from the ground.  Seeds are eaten while clinging to a grass or weed stalk and plucking seeds, or by consuming fallen seeds from the ground.

Nesting: June and July in South Dakota. The nest of a Dickcissel is a dense cup built of grasses, weeds, and other vegetation, placed just above the ground in a clump of grass or low in a small shrub.  The female lays between 3 and 6 eggs and she alone incubates them. Incubation lasts about 13 days. The female alone also feeds and cares for the young until they fledge.

Song: Click to hear Dickcissel Song. The song in general is a dry dick-dick CISS CISS CISS, with the last syllables higher in pitch.

Migration: Neotropical migrant, summering in the U.S. and wintering in Central and South America.

Similar Species: Male generally distinctive, although the color pattern may resemble the much larger Western Meadowlark

Bird Feeders: Will occasionally come to feeders for small seeds and grains.

South Dakota "Hotspot" - Any grassy pasture or alfalfa field in the eastern part of the state could hold Dickcissels.  They are a very common sight in the farm and pasture land of eastern South Dakota, where they are readily visible as they sing from fence posts, telephone lines, shrubs, or any other perch that rises above the surrounding landscape. Despite their size, their characteristic song carries a fairly long distance, leading to easy detection of the species even when the bird itself can't be seen.

Conservation Status: Once a fairly common breeder in the Atlantic states, but disappeared as a breeding species there by 1900. This may be due to a "reforesting" of the East, after widespread deforestation in the 1800s and early 1900s left much more open land in the Eastern US than is there today.   While reestablishing itself in pockets in the east, some local declines have occurred elsewhere in its range.  Dickcissels often nest in alfalfa fields, sometimes resulting in large numbers of young being lost when the fields are mowed before the young can fledge.  Dickcissels are also one of the most common hosts for Brown-headed Cowbird parasitism. Despite the challenges facing the species, however, overall numbers are strong and considered to be relatively stable. The IUCN lists the Dickcissel as a species of "Least Concern".
