Family Tyeannidab. Tyrant Flycatchers. 



Tyrannus tyeannus (Linn.). Kingbird. 



Common summer resident. 



The first Kingbirds arrive between the 18th and 26th of April, 

 followed during the next ten days by swarms of migrants. The 

 return flight is noticeable as early as the 29th of August and 

 continues for about three weeks. 



This flycatcher is fairly common within the city and is a 

 familiar bird everywhere in the surrounding country. 



A favorite roosting place for great numbers during the period 

 of flocking that precedes migration is in the miles of willow 

 bottoms along the Missouri River below the Milwaukee Bridge. 



Tyeannus veeticalis Say. Arkansas Kingbird. 

 Occasional visitant during migration and summer. 



An unusual visitation of Arkansas Kingbirds occurred on 

 the Bankers' farm in Holt County during the late summer of 

 1917 when nine specimens were recorded. Prior to this time 

 there were but two known records for this region: May 31, 

 1899, and May 9, 1913, both specimens being taken by Bankers. 

 There are but three other known records for the entire state of 

 Missouri. 



Mtiaechus crinitus (Linn.). Crested Flycatcher. 

 Very common summer resident. 



The Crested Flycatcher arrives from the 23rd to 28th of 

 April (in the following years it arrived promptly on the 27th of 

 April: 1899, 1900, 1901, 1904, 1916 and 1917). An excep- 

 tionally early date for this bird was April 15, 1915. (See table 

 of arrival dates given under the Phoebe). It leaves for the 

 south during the first week or ten days in September. 



This noisy bird comes freely into the city to nest in cavities 

 in trees or in bird boxes. It has a very sharp eye for cast snake 

 skins which it usually includes in the nesting material. In the 

 city bits of thin or greasy paper or onion skins are substituted. 



The eggs, laid in June, are four to seven in number and beau- 

 tifully marked with streaks and wavy lin es, 



It may be looked for in all wooded parts of the county.
