Top Ten Winter Bird Feeding Tips

White-Breasted Nuthatch

10. Make sure seed is accessible and dry. Hopper or tube feeders are good at protecting seed from wet weather. Sweep snow off of platform feeders, or clear a place on the ground where you can scatter seed for ground-feeding species such as sparrows, towhees, juncos, and doves.

9. Make a windbreak. Make a windbreak using your old Christmas tree or the remains of a brush pile. Consider planting shrubs next to your feeders where the birds can rest out of the wind and escape from predators. Consider clearing a small area of snow off the ground to scatter seed if it's too soft to support their weight.

8. Keep extra feeders for use in bad weather. We keep an extra-large-capacity tube feeder in the garage for use when nasty weather comes. It not only gives the birds another place to eat, which means more birds can eat at one time, but it also cuts down on our trips outside for refilling the feeders. Other extras to consider having: peanut feeder, suet feeder, satellite feeder (for the small birds to use), and a hopper feeder.

7. Scatter seed in sheltered places. Not all birds will venture to your feeder. Some species prefer to skulk in the thickets, brambles, and other secure places. For these species, consider scattering some seed (black-oil sunflower, sunflower bits, peanut bits, mixed seed) under your deck, in your hedges and bushes, or even along the edge of a wooded area. Dark-eyed juncos especially prefer to feed on food scattered on the ground along with tree sparrows and white-throated sparrows.

6. Put out high-energy foods such as suet, meat scraps, and peanut butter. Fat gives the biggest energy boost to winter birds and without enough energy to keep them going, many songbirds would not survive a cold winter night. Suet (the fat removed from processed beef), meat scraps, and peanut butter all provide fat to birds that eat them. If you don't have a suet feeder, use a mesh onion bag. Suspend it from a tree branch or iron feeder hook. To feed peanut butter, drill one-inch holes in a foot-long section of a small log. Insert a screw eye into one end of the log. Smear peanut butter into the holes and suspend the feeder from the screw eye. And, no, peanut butter will not stick to the roof of a bird's bill and choke it to death.

5. Use a birdbath heater wisely. A water heater can keep your birdbath open in the coldest of weather, which is good but place several large rocks in your bath so there is not enough room for a bird to bathe, but still plenty of places for a thirsty bird to get a drink. When the weather warms up you can remove the rocks and let your birds get on with their hygiene.

4. Offer mealworms in a heavy dish or small crock. Use a heavy dish so the wind can't blow the worms and dish away. This is a high protein snack that many birds enjoy and can be found in most feed stores. They are relatively expensive so use them sparingly on the coldest days or in the spring when an unexpected cold snap can leave migrants without much to eat.

3. Furnish your bird houses. Imagine you're a bird roosting in a nest box on a cold winter's night. Wouldn't it be nice to snuggle down into some dried grass or dry wood shavings in the bottom of the house? Layer three to four inches of clean dry meadow grass in the bottom of bluebird boxes after the last nesting of the summer. Wood shavings work well, too. Don't use sawdust, however; it can retain moisture once wet, which does not help the birds keep warm.

2. Plug the air vent holes in your bird houses with removable weather stripping. We use the claylike weather stripping that comes in a roll (Moretite is one brand) to plug the air vent holes in our bird houses. Good ventilation is necessary on a scorching summer day, but it's a real liability for birds seeking winter shelter. Think how cozy the birds will be in a well-sealed house.

1. Be ready for big changes in weather. If you keep abreast of the weather developments you'll know when bad weather is coming, and you'll be able to stock up on seed, suet, and other goodies. You can also be ready to take on some of the activities listed above. Conversely, when the weather breaks, take advantage by cleaning and disinfecting your feeders (one part bleach to nine parts hot water). Whatever you do, don't let yourself be caught totally unprepared for harsh winter weather.

What can I do with my wetland?

Whether you call it a swamp, marsh, or low area, it is most likely a wetland and it is most likely regulated by someone.

ExcavatingAnoka County residents frequently inquire how to improve their land for waterfowl or other wildlife. A common practice in Anoka County is pond excavations in seasonally saturated areas, or cattail-choked wetlands to provide an open water habitat. The Wetland Conservation Act regulates excavations in the permanently and semi-permanently flooded areas of type 3, 4, or 5 wetlands and also regulates the placement of spoil and the depth of the excavation in all types of wetlands. Other jurisdictions including the US Army Corps of Engineers and the Minnesota Department of Natural Resources may have regulatory authority on wetland excavation projects.

DrainingThere is potential for pond excavations to drain adjacent wetland areas. Typically, in Anoka County, if the hydrology is predominantly groundwater driven, a pond excavation can be designed that will not drain adjacent wetlands. However, there is an increased likelihood that a pond excavation will drain adjacent wetlands when wetlands hydrology is primarily surface water, or when the excavation is connected to a drainage ditch. This is an issue that is best addressed by your local government or the Anoka Conservation District during review of a specific project.

Filling: Filling of wetlands must be avoided during pond excavations. The spoil from the excavation must be placed in an upland area. A qualified wetland professional may be needed to ensure that the destination of the spoil is upland.

Proper erosion control practices must be incorporated as well. If you have questions, contact the Anoka Conservation District for assistance. Contact us.

2019 Precipitation in Minnesota

2019 was another banner year for precipitation in Minnesota, with over 20 individual annual precipitation records set, and the state turning in its wettest year on record.

Precipitation totals for the year exceeded 30 inches over all but about 5-10% of the state, mainly in far northern Minnesota, with totals exceeding 50 inches in parts of southern and southeastern Minnesota. Well over half of the state was 12-20 inches (or 50-70%) wetter than normal. Annual surpluses of that magnitude over such a large area contributed to 2019 being Minnesota's wettest year on record, on a statewide-average basis, with an average of 35.51 inches. This eclipsed the old record of 33.93 inches, set in 1977.

Although no climate observing station was able to break the statewide individual annual precipitation record of 60.21 inches set by Harmony in 2018, many stations with over 50 years of observations did break their own annual precipitation records. Rochester International Airport led the pack with 55.16 inches, breaking its old record by more than 11 inches.

The Twin Cities International airport, part of the longest station history in the state, had just broken its record in 2016, but broke it again in 2019, with 44.17 inches. Other records fell throughout the state. The majority of these stations broke records that had been set this decade.

Even closer to home, the ACD has utilized the precipitation data collected by our volunteer observers to assist with putting our monitoring well data in context. We have observed sustained wetland hydrology because of the abundance of precipitation. How this will affect how wetlands are managed in the present and future will need to be addressed by the current wetland regulatory rules and by utilizing the data we collect when reviewing wetland delineations.

You don't want to be underneath this mistletoe: the Eastern Spruce Dwarf Mistletoe


by Fred Baker, Emeritus Professor and Forest Pathologist, Utah State University

Eastern spruce dwarf mistletoe is a disease that kills trees quickly, with most trees dying within 20 years. In Minnesota, this mistletoe typically affects black spruce, an important species to the state's forest products industry and landscape.

The dwarf mistletoe disrupts a tree's physiology in incredible ways. The most common sign is the formation of a witches' broom. In this process, the disease diverts the tree's nutrients to the broom and "starves" the rest of the tree. Ultimately, the tree will die because it's unable to process the lipids it needs to survive.

Dwarf mistletoe is a parasite. It flowers in March and is a safe bet to be the first "plant" to flower in the spring. Seed dispersal happens in late August and early September. When seeds disperse, dwarf mistletoes are unique because they can shoot their seeds up to 55 feet from a diseased tree! These seeds are covered with a sticky substance that attaches to a nearby spruce needle. During summer rainfall, this sticky substance rehydrates, and the seeds slide closer to the twig, where it germinates the following spring.

Although dwarf mistletoe can shoot seeds up to 55 feet, most only go a few feet. This results in a spread rate of about 2.4 feet per year through a forest stand. Research indicates that spread from large trees and small trees is about the same. Slightly more than half the spruce stands in Minnesota are thought to be infected with dwarf mistletoe.

Mistletoes are obligate parasites. This means that if you kill the tree, the parasite dies too. If timber harvesting is done in black spruce, removing all spruce trees during a harvest could minimize the risk of mistletoe infecting a future stand.
